The association between an exposure of interest (risk factor) and a disease may be confounded by the action of other separate factors as well as by interactions between risk factors exerting an impact. Crude measures of effect may be misleading in such situations. Levels of the potential confounding factor could be estimated using stratified analysis. Uniformity of the stratum-specific effect estimates can be assessed by performing chi-square tests for heterogeneity. If the effect is uniform… CONTINUE READING
