Predicting health facility deliveries using explainable machine learning in Sidama Region, Ethiopia: A prospective cohort study.
Article in Women's health (London, England). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHealth facility delivery (HFD) is a key intervention for reducing maternal and neonatal morbidity and mortality. However, a substantial proportion of women in Ethiopia continue to give birth at home. Early identification of women at risk of home delivery is essential to support targeted maternal health interventions.
objectiveThis study aimed to predict HFD utilization using machine learning (ML) models and to identify key determinants of delivery service uptake in the Sidama Region of Ethiopia.
designA prospective cohort study was conducted among 3855 pregnant women who initiated antenatal care (ANC) in public health facilities across 4 districts of the Sidama Region between January 2021 and January 2025.
methodsData were analyzed using the R software version 4.3.1 (R Core Team, R Foundation for Statistical Computing, Vienna, Austria). Predictive models - including logistic regression, random forest, gradient boosting, and extreme gradient boosting (XGBoost) were developed to predict HFD utilization. Model performance was assessed using accuracy, sensitivity, specificity, F1-score, and the area under the receiver operating characteristic curve (AUC-ROC). SHapley Additive exPlanations (SHAP) were used to identify the most influential predictors.
resultsOverall, 59.2% of women delivered in health facilities, while 40.8% delivered at home. Among the evaluated models, XGBoost demonstrated the highest predictive performance, achieving an accuracy of 86.9% (95% confidence interval (CI): 85.6-88.1) and an AUC-ROC of 0.91 (95% CI: 0.90-0.93). SHAP analysis identified place of residence, maternal education, timing of ANC initiation, parity, and distance to the nearest health facility as the most influential predictors. Rural residence, lower educational attainment, late ANC initiation, higher parity, and greater distance to health facilities were associated with a lower likelihood of HFD utilization.
conclusionDespite improvements in HFD utilization, a substantial proportion of women in the Sidama Region continue to deliver at home. ML models offer a robust approach for identifying women at high risk of home delivery and supporting targeted, data-driven interventions. Strategies that promote early ANC engagement, maternal education, improved geographic access to health facilities, and integration of predictive analytics into health systems may enhance HFD utilization.
