Effect of population screening for type 2 diabetes

Effect of population screening for type 2 diabetes
by Medical Xpress August 24, 2017
"Three large trials published today in Diabetologia (the journal of the European Association for the Study of Diabetes) show that screening for type 2 diabetes and cardiovascular risk factors may not reduce mortality and cardiovascular disease in the general population. However, for individuals diagnosed with diabetes, screening is associated with a reduction in mortality and cardiovascular disease risk. " full text

how to estimate the risk and relative risk from logistic regression

How to estimate the risk and relative risk from logistic regression of a case-control study (OR to RR)
One advantage of odds ratios is that we can estimate it in a case-control study, when we usually oversample the cases. However, we cannot directly calculate the probability using logistic regression in a case-control study, since the beta(0) of the case-control study cannot represent the target population, which beta(0) of the target population is equal to beta(0) of the case-control study - log(sampling probability for cases/sampling probability for controls).
