Disadvantage of cohort study?
One disadvantage of a cohort study is the potential for loss to follow-up, which can introduce bias if the characteristics of those lost differ systematically from those who remain. Additionally, cohort studies can be time-consuming, resource-intensive, and require a long follow-up period to observe outcomes, making them impractical for some research questions. Bias in exposure assessment or outcome measurement can also affect the validity of results in cohort studies.
Why is a case-control study often referred to as a retrospective study?
A case-control study is referred to as a retrospective study because it looks back in time to study the exposure history of cases (individuals with the outcome/disease) and controls (individuals without the outcome/disease).

What is a blind trial?
A blind trial is a trial in which the subject does not know if he is part of the experimental group or the control group. In the case of a pharmaceutical trial, a blind study would be one in which the patients participating in the study would not know if they were being given the actual drug or a placebo. A double-blind trial is one in which neither the patients nor the doctors involved in the study know which patients are in the control group and which patients are in the experimental group.
