Description
85 studies on stepped-wedge designs in sub-Saharan Africa were systematically reviewed, involving a total of 1,895,788 participants. The review, authored by Zaidat Adesola Musa and published in 2026, covers studies from January 2000 to March 2024 across diverse health domains like HIV/AIDS and maternal health.
Use Cases
Analyze the distribution of study characteristics like facility-based versus community-based settings across the 85 reviewed studies.
Examine the relationship between the number of clusters and the number of steps used in different stepped-wedge design implementations.
Map the geographic and health domain coverage of studies, such as HIV/AIDS or malaria interventions, across sub-Saharan Africa.
Review the statistical methods and sample size calculations, including assumptions like intra-cluster correlation coefficients, detailed in the included studies.
Strengths
The review synthesizes data from 85 distinct studies, providing a broad evidence base.
It aggregates findings from a total participant pool of 1,895,788 individuals across all included studies.
The methodology followed a registered PRISMA protocol, ensuring a systematic and transparent review process.
The temporal coverage spans over 24 years, from January 2000 to March 2024.
Limitations
The dataset is a single 169.1 KB PDF document, containing only the review's text and not the underlying raw data from the 85 studies.
As a systematic review, the data consists of summarized findings and extracted study characteristics, not primary observational or experimental records.
The scope is limited to studies using stepped-wedge designs in sub-Saharan Africa, which may not be generalizable to other methodologies or regions.
