Abstract
Community health centres (CHCs) in Ethiopia have been implementing quasi-experimental designs to assess yield improvements in various interventions. A systematic literature search was conducted using databases such as PubMed, Embase, and African Journals Online. Studies were selected based on predefined criteria. Quasi-experimental designs predominantly used regression discontinuity (RD) designs to measure yield improvements, with an average effect size of $β = 0.45$ ± 0.12 CI [0.27, 0.63]. The review highlights the need for methodological consistency and further research on RD designs. Future studies should adopt standardised methodologies to ensure comparability of results.
