There are a few strenghts of case-control design of the study. Firstly, it is quite efficient for rare outcomes. The major strength of case-control study is its rapid, high yield information from relatively few subjects. For diseases that are either rare or have long latent period between the exposure and disease, case-control study is not only far more efficient than other study designs, they are often the only feasible option. Case-control study is also useful to generate hypotheses.The retrospective approach of case-control study and the abilities to examine a large number of predictor variables will make them useful to generate hypotheses about the casues of a new outbreak of disease.
