Retrospective cohort study

[@MrEljonni]

For clarity, you should have compared case control to retrospective cohort in your example

Remy! A very basic difference between the cross sectional (comparative)and and retrospective cohort study is that in cross sectional study the direction of causation is not known i.e both the cause and effect are present at the same time and we can not say which one is the cause and which one is the effect, while in retrospective cohort study we know the direction

[@albiner1999]

Remy - cross sectional studies are basically of two different types - 1) a descriptive cross-sectional whereby distribution of outcome (usually disease, may be something else) are quantified with other basic descriptive statistics presentation and 2) analytical cross sectional whereby relations are made between independent variables and outcome via 2 X 2 tables and other inferential statistics; of course basic descriptive statistics are presented here. Comparative cross sectional would fall into analytical design whereby you have two different population (for instance year 1 vs year 5 medical students) with same outcome measured (for instance emphaty).
Now retrospective just indicates that the outcome is already present at the commencement of the study - hence cross sectional, case control and retrospective cohort (retrospective cohort usually involves secondary data analysis) would fall into retrospective design.
Retrospective needs to be differentiated with prospective and not cross sectional - here prospective would mean that outcome is not present at the commencement of the study such when we conduct prospective cohort
