Effectiveness of Community Health Workers in Malaria Control: A Systematic Review in West African Coastal Regions, Ghana
Bibliographic record
Abstract
Malaria remains a significant public health issue in West African coastal regions of Ghana, despite ongoing efforts to control its spread. A comprehensive search strategy was employed using electronic databases such as PubMed, Embase, and Web of Science to identify relevant studies published between and . Studies were selected based on predefined inclusion criteria and assessed for methodological quality using the Newcastle-Ottawa Scale. The review identified a significant improvement in malaria case detection rates among community members, with an estimated proportion increase of 35% over twelve months after CHW interventions. CHWs play a crucial role in malaria control and their effectiveness can be enhanced through continuous feedback loops to improve intervention strategies. Integrating CHWs into existing health systems is recommended, alongside the establishment of robust monitoring and evaluation frameworks to ensure sustainable impact. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
