Hypertension in Zimbabwe: A meta-analysis to quantify its burden and policy implications

Figure 1 Flow diagram of the study selection process. As shown in Figure 1, our initial search yielded 87 citations: 18 from MEDLINE, 36 from EMBASE, 28 from Scopus, and 5 from grey literature. After screening titles and abstracts, 22 studies were considered potentially eligible and retrieved in full text. Of these, 18 studies were subsequently excluded because they did not satisfy the inclusion criteria. Thus, four fully eligible studies were identified.
