Observational studies are categorized into four different types: case series studies, case–control studies, cross-sectional studies and cohort studies. A case series is a study on a group of patients based on an observation of a specific disease. Lack of a control group in this type of study is a major disadvantage.

It is this situation that should be avoided. However, if one of the aims of the meta-analysis was to understand if study design was a source of methodological heterogeneity, then including data from observational studies achieves that aim. The reasons that study design was associated with different effect measures should be explored.
