In retrospective studies where you select subjects by outcome not by group characteristic then you would use the odds ratio ((a/c)/(b/d)) and not the relative risk. All participants then took the Risk Preference Quiz and reported their scores. In addition, new chapters introduce more advanced topics such as meta-analysis, likelihood, bootstrapping and robust standard errors, and analysis of clustered data. One and two-sided intervals are supported for both the risk ratio and the Number Needed to Treat (NNT) for harm or benefit. Approximate power is calculated as the power achieved with the given sample size to detect the observed effect with a two-sided probability of type I error of (100-CI%)% based on analysis with Fisher's exact test or a continuity corrected chi-square test of independence in a fourfold contingency table (Dupont, 1990). The relative risk calculator can be used to estimate the relative risk (or risk ratio) and its confidence interval for two different exposure groups. If this is the case, the risk ratio = 1, the risk difference = 0, and the excess relative risk = 0. return to top | previous page | next page, Content 2021.
