Last reviewed 01/2018
Type of study:
- retrospective e.g. case control study
- prospective e.g. cohort study, randomised controlled trial
Other points regarding study design include:
- was the study blinded? If so was the study blinded for the patient and the investigator (double blinded)?
- was the study a crossover study?
The findings from a prospective study are more valid than those from a retrospective one.
