Stepped-Wedge Design Studies in Sub-Saharan Africa Systematic Review

85 studies from a systematic review of stepped-wedge designs in sub-Saharan Africa, covering health domains like HIV/AIDS and maternal health. The review includes data on 1,895,788 total participants and details study characteristics, implementation, and statistical methods. It was authored by Zaidat Adesola Musa and covers literature from January 2000 to March 2024.

Use Cases

• Analyze the distribution of study characteristics like facility-based (84.7%) versus community-based (15.3%) settings across the 85 studies.
• Model the relationship between the number of clusters (from 4 to 54) and the number of steps (from 2 to 12) used in different stepped-wedge designs.
• Examine sample size calculations and the assumed intra-cluster correlation coefficient across the included studies to inform power analysis for future designs.

Strengths

• Includes 85 studies identified through a systematic review of 873 titles and abstracts.
• Covers a total participant population of 1,895,788 individuals across the reviewed studies.
• Provides a detailed temporal scope, reviewing literature from January 2000 to March 2024.

Limitations

• The dataset is small in file size (18.9 KB), indicating limited raw data, likely consisting of summary tables rather than detailed participant-level records.
• Specific column names and sample data are unavailable, limiting immediate analysis of individual study variables.
• Findings are constrained to sub-Saharan Africa, limiting generalizability to other geographic regions.
