Interrupted time series must have at least 3 measurement points prior to and after the intervention is begun. The Role of Inclusion and Exclusion Criteria in Clinical Research . Although the term population is also used in qualitative reviews, its use doesn't imply that all of the features relevant to quantitative reviews such as sampling methods or homogeneity (which refers to similarity among included studies' results) are appropriate here.
