· The risk ratio (RR), also called the relative risk, is the ratio of the probability of cancer in smokers to the probability of cancer in nonsmokers RR = (a/ (ab))/ (c/ (cd)) = (a (cd))/ (c (ab)) Given that you know a, b, c, and d, you can compute either of these metricsAlso I have difficulty understanding different study designs and ends up misinterpreting them Is there an easier way of understanding the difference between cohort studies, case control studys, retrospective cohort studies and crosssectional studiesThis implausible scenario is shown in Table 5, where collapsed counts for low (or high) risk subjects only produce a 2 × 2 table with an odds ratios of 400
