What is the Difference Between Case Series and Cohort Studies?
While both case series and cohort studies involve groups of individuals, there are key differences: - Design: Case series are descriptive and do not include a comparison group, whereas cohort studies are analytical and involve following groups over time to compare outcomes between exposed and unexposed groups. - Causality: Cohort studies are better suited for establishing causality because they can control for confounding factors and include a control group. - Purpose: Case series are often preliminary and hypothesis-generating, while cohort studies aim to test specific hypotheses and establish causal relationships.
