Document Summary
Analytic format for calculating or, rr, and attributable risk. C/(c+d: a = with disease & with exposure, b = w/o disease but with exposure c = with disease but no exposure, d = w/o disease & w/o exposure, odds: the chance or likelihood, mainly used in case-control. * identifying and accessing entire cohort would be too costly or time consuming. Calculating or vs. rr if disease is infrequent (rare) the or and rr will be very similar if disease is not infrequent the or and rr will be different. Experimental study (rct) compared to case-control and cohort studies (cid:449)here they are o(cid:271)ser(cid:448)atio(cid:374)al, rct"s experimental!! subjects are randomly allocated to the exposed or not exposed groups. Socio-ecological model of health level of intervention: socio-ecological perspective. * screening for cholesterol in children restricted to children from high-risk families. * more expenzive and is often more invasive/inconvenient. * required a clinical action to identify the high-risk group.
