For example discount 100 mg januvia with visa diabetes type 2 interventions, say that we compare men and women on the dependent variable of cre- ativity cheap januvia 100 mg otc diabetes zits. In nature purchase januvia from india diabetes mellitus type 2 case history, men and women don’t really differ on this variable, so their s are equal. However, through sampling error—the luck of the draw—we might end up with some female participants who are more creative than our male participants, or vice versa. Then sampling error will mislead us into thinking that this relationship exists, even though it really does not. Or, say that we measure the heights of some men and women and, by chance, obtain a sample of relatively short men and a sample of tall women. If we didn’t already know that men are taller, sampling error would mislead us into concluding that women are taller. Researchers perform inferential statistics in every study, because it is always possi- ble that we are being misled by sampling error so that the relationship we see in our sample data is not the relationship found in nature. Previously we’ve said that inferential statistics are used to decide if sample data represent a particular relationship in the population. Using the process discussed in the previous chapter, the decision boils down to this: (1) Should we believe that the Setting Up Inferential Procedures 209 relationship we see in the sample data is generally the same as the relationship we would find if we tested the entire population? The specific inferential procedure employed in a given research situation depends upon the research design and on the scale of measurement used when measuring the dependent variable. We have, however, two general categories of inferential statistics: Parametric statistics are procedures that require specific assumptions about the char- acteristics of our populations. Thus, parametric procedures are used when it is appropriate to compute the mean in each condition. The other category is nonparametric statistics, which are inferential procedures that do not require stringent assumptions about our populations. These procedures are used with nominal or ordinal scores or with skewed interval or ratio distributions (when it is appropriate to calculate the median or mode). As we’ll see, parametric procedures are often preferable, so typically we use non- parametric procedures only when the data clearly violate the assumptions of paramet- ric procedures. Instead, we can use a parametric procedure if the data come close to meeting its assumptions. For example, if our population is approximately normally dis- tributed, we can still use a parametric procedure. As you’ll see, both parametric and nonparametric procedures are performed in the same way. Creating the Experimental Hypotheses Recognize that the purpose of all experiments is to obtain data that will help us to resolve the simplest of debates: maybe my independent variable works as I think it does versus maybe it does not. Experimental hypotheses describe the predicted relationship we may or may not find. One hypothesis states that we will demonstrate the predicted relationship (manipulat- ing the independent variable will work as expected). The other hypothesis states that we will not demonstrate the predicted relationship (manipulating the independent vari- able will not work as expected). Sometimes we expect a relationship, but we are not sure whether scores will increase or decrease as we change the independent variable. A two-tailed test is used when we predict a relationship but do not predict the direction in which scores will change. Notice that a two-tailed test occurs when we predict that one group will pro- duce different dependent scores than the other group, without saying which group will score higher. For example, we have a two-tailed test if we propose that “men and women differ in creativity” or that “higher anxiety levels will alter participants’ test scores. A one-tailed test is used when we predict the direction in which scores will change. We may predict that as we change the independent variable, the dependent scores will only increase, or we may predict that they will only decrease. Notice that a one-tailed test occurs when we predict which group will have the higher dependent scores. For example, we have a one-tailed test if we predict that “men are more creative than women” or that “higher anxiety levels will lower test scores. A one-tailed test is used when you do predict the direction that scores will change. Remember, however, that ultimately researchers want to describe what occurs in nature, in what we call the population. Therefore, although we must first see that the independent variable works as predicted in our sample, the real issue is whether we can conclude that it works in the population. Designing a One-Sample Experiment There are many ways we might design a study to test our pill, but the simplest way is as a one-sample experiment. We will randomly select one sample of participants and give each person, say, one pill. The sample will represent the population of people who have taken one pill, and the sample X will rep- resent the population. Therefore, we must compare the population represented by our sample to some other population receiving some other amount of the pill. To perform a one-sample experiment, we must already know the population mean under some other condition of the independent vari- able. Here our independent variable is the amount of the pill taken, and one amount that we already know about is zero amount. Setting Up Inferential Procedures 211 We will compare this population that has not taken the pill to the population that has taken the pill that is represented by our sample. If the population without the pill has a different than the population with the pill, then we will have demonstrated a relationship. Creating the Statistical Hypotheses So that we can apply statistical procedures, we translate our experimental hypotheses into statistical hypotheses. We are still debating whether our independent variable works, but now we state this in terms of the corresponding statistical outcomes. Statis- tical hypotheses describe the population parameters that the sample data represent if the predicted relationship does or does not exist. The two statistical hypotheses are the alternative hypothesis and the null hypothesis. The Alternative Hypothesis It is easier to create the alternative hypothesis first because it corresponds to the experimental hypothesis that the experiment does work as predicted. The alternative hypothesis describes the population parameters that the sample data represent if the predicted relationship exists. The alternative hypothesis is always the hypothesis of a difference; it says that changing the independent variable produces the predicted difference in the populations. We don’t know how much scores will increase, so we do not know the value of the new with the pill. But we do know that the of the population with the pill will be greater than 100 because 100 is the of the population without the pill.
A clinical trial by research- ers at the University of Chicago has demonstrated the predictive signiﬁcance of genotyping for variants that affect drug pharmacodynamics order januvia 100 mg visa type 1 diabetes definition dictionary. The toxic effects were found only in patients who possessed at least one allele of that polymorphism cheap generic januvia canada diabetes prevention trial testosterone. Concluding Remarks on the Economics of Personalized Medicine Several studies point to beneﬁts of personalized medicine by improving efﬁcacy and safety buy cheap januvia 100 mg on line diabetes diet tracker. From an ethical point of view, a physician is required to recommend the best available treatment. The pharmaceutical indus- try is adapting to development of trend in personalized medicine, but some contro- versies need to be resolved. Although case studies of application of personalized medicine have shown beneﬁt for patients and cost-effectiveness, the barrier to large-scale real-world adoption of this approach requires a change in health policy. Universal Free E-Book Store 692 23 Economics of Personalized Medicine At point-of-care, the case studies personalized medicine will need to measure outcomes, which are important for policy-makers, as evidence of clinical utility (van Rooij et al. Personalized medicine and the role of health economics and outcomes research: issues, applications, emerging trends, and future research. Personalized medicine policy challenges: measuring clinical utility at point of care. Universal Free E-Book Store Chapter 24 Future of Personalized Medicine Introduction Several studies of the human genome are still going on and some are planned. Ongoing Studies Personal Genome Project Achieving personalized medicine will require extensive research on highly re- identiﬁable, integrated datasets of genomic and health information. These resources were planned to include full (46-chromosome) genome sequences, digital medical records and other medical information that would become a part of personal health proﬁle. Human cell lines representing each subject are deposited in a repository at the National Institute of Genome Medical Sciences. To that end the team developed a peer production system for recording and organizing variant evaluations according to standard evidence guidelines, creating a public forum for reaching consensus on interpretation of clinically relevant variants. Genome analysis becomes a two-step process: using a prioritized list to record vari- ant evaluations, then automatically sorting reviewed variants using these annota- tions. Genome data, health and trait information, participant samples, and variant interpretations are all shared in the public domain. There is an open invitation to others to review the results using participant samples and contribute to interpreta- tions. This public resource and methods are offered to further personalized medical research. The differences may point to genetic risk factors for the development or progression of disease. This will be an important contribution to genomics-based health care and personalized medicine. Data will be submitted in a form that protects the privacy and conﬁdentiality of research participants. The data will be made freely available to all approved researchers to accelerate their studies. Data will be released in a manner that preserves the privacy and conﬁden- tiality of research participants. A thousand persons will have their genomes sequenced in an ambitious 3-year project that will create the most comprehensive catalogue so far of human genetic variation. These volunteers have already been recruited from Africa, Asia, America, and Europe. The donors are anonymous and will not have any of their medical informa- tion collected because the project is developing a basic resource to provide information on genetic variation. The goal of the 1000 Genomes Project is to uncover the genetic variants that are present at a frequency of 1 % or more in the human genome. Three 1000 Genomes pilot projects, which began in 2008 aim to achieve low coverage of 180 individuals, high coverage of two parent-offspring trios, and targeted sequencing of 1,000 genes in approximately 1,000 individuals, are nearing completion. Those efforts seem to be generating high-quality data and have already uncovered new genetic variants. So far, the 1000 Genomes Project has Universal Free E-Book Store 696 24 Future of Personalized Medicine generated 3. In 2009, the project is expected to up that dramati- cally, producing a petabyte of data. Beyond the direct implications for the 1000 Genomes Project, the effort has spurred researchers to pioneer and evaluate methods that beneﬁt other research efforts as well. There a need, however, for developing shared data formats for different stages of the analysis. In the absence of standard formats or a clear framework for such analysis, efforts to decipher the genetic information would be delayed. Consequently, team members are working to develop draft formats to aid this analysis. A better understanding of the genetic causes of longevity could have a major impact on the Indian Government’s healthcare bud- get and drug companies’ marketing efforts. The use of Affymetrix technology will enable researchers to correlate genes with longevity, as well as neurodegenerative condi- tions, breast cancer, diabetes and other complex diseases that affect the Parsi com- munity. The Parsi community was selected because of its longevity and its relatively genetically homogeneous population. This project takes a systems biology approach that encompasses not only genotyping but also expression proﬁling and transcrip- tomics. The genotyping phase of the project, which began in 2007, consisted of 10,000 samples in the ﬁrst year. By the middle of 2008, the team had performed expression proﬁling and transcript mapping experiments across a subset of the sam- ples.. Data conﬁdentiality is being maintained as in accor- dance with the Indian Council of Medical Research guidelines. Translational Science and Personalized Medicine Translational science deals with transfer of technologies from preclinical research into clinical application. There is a need for a comprehensive research agenda to move human genome discoveries into health practice in a way that maxi- mizes health beneﬁts and minimizes harm to individuals and populations. A frame- work has been presented for the continuum of multidisciplinary translation research that builds on previous characterization efforts in genomics and other areas in health care and prevention (Khoury et al. The continuum includes four phases of trans- lation research that revolve around the development of evidence-based guidelines: • Phase 1 translation (T1) research seeks to move a basic genome-based discovery into a candidate health application (e. Because the development of evidence-based guidelines is a moving target, the types of translation research can overlap and provide feedback loops to allow inte- gration of new knowledge. Although it is difﬁcult to quantify genomics research is T1, no more than 3 % of published research focuses on T2 and beyond. With continued advances in genomic applications, however, the full continuum of translation research needs adequate support to realize the promise of genomics for human health. Eventually, researchers hope to determine whether participating in personal genomic testing spurs individuals to make beneﬁcial lifestyle changes such as improving their diet and exercise regimes. The team plans to track participants’ lifestyle changes using self-reported health questionnaires.
