Do you seek for 'cross sectional study vs case control vs cohort'? You will find all of the details here.
From an analytic stand the cross-sectional cogitation is weaker than either a age bracket or a case-control study because letter a cross-sectional study unremarkably cannot disentangle hazard factors for happening of disease (incidence) from risk factors for survival with the disease.

How are case control and cohort studies related?
As we will see later, the incidence in different groups in a cohort study is compared using Relative Risk (RR). Case-Control Studies are retrospective and observational. You first identify people who have the health outcome of interest.
How are retrospective and cross sectional cohort studies different?
Retrospective cohort studies use the data that is already obtained for other reasons. Retrospective follow up of the cohort is done. Prospective Cohort study is s uitable for rare exposures. The incidence rate and the relative risk of the disease can be determined.
What's the difference between case control and cross sectional studies?
Cross -sectional studies, case control studies and cohort studies are all types of analytical epidemiological studies. All have individual as unit of study. The difference lies in the design of the study.
How are cohort studies different from experimental studies?
Note that this differs from an experimental study because, in a cohort study, the investigator observes rather than determines the participants’ exposure status. After a period of time, the investigator compares the disease rate in the exposed group with the disease rate in the unexposed group.
