Abstract:
Retrospective studies are still very important in clinical decision making although they present severe methodological deficiencies compared to controlled trials. Imprecise and incomplete data gathering, lack of homogeneity in the group studied, and lack of randomisation are the main drawbacks. Indications for retrospective studies and criteria for their execution are presented.
