Application of Machine Learning Algorithms for Predicting Infant Mortality in India: An Analysis of the National Family Health Survey-5, 2019-2021.
Article in Healthcare informatics research, 2026. 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
objectivesMachine learning (ML) techniques have shown strong potential for predicting infant mortality (IM), but their application in the Indian context remains limited. This study aimed to use ML algorithms to predict IM in India using a large national survey database.
methodsData were analyzed from the National Family Health Survey-5, 2019-2021, a large cross-sectional survey. Random forest, decision tree, adaptive boosting, logistic regression, and naïve Bayes models were implemented using Weka version 3.8.3. Model performance was evaluated using accuracy, precision, F1-score, Matthews correlation coefficient, and area under the curve (AUC).
resultsCompared with logistic regression, which achieved 65.2% accuracy, the random forest and decision tree models showed higher predictive accuracy, at 74.1% and 73.2%, respectively. Their AUCs were 0.80 and 0.79, respectively, compared with 0.69 for logistic regression. The models identified birth order, maternal education, twin birth, wealth index, cooking fuel use, and age at first birth as the six strongest predictors of IM.
conclusionsIn this analysis, random forest and decision tree models outperformed logistic regression in predicting IM. These findings underscore the relevance of sociodemographic and economic disparities and support the use of ML algorithms for risk prediction and targeted interventions aimed at reducing IM.
