Article in Indian journal of community medicine : official publication of Indian Association of Preventive & Social Medicine, 2025. 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
Background: Birth weight plays a vital role in an infant's comprehensive development. Low birth weight (LBW) infants may go through several kinds of health complications in the early stages of their lives. This paper is an attempt to identify the predictors that significantly influence the likelihood of LBW through a model-based approach. Methodology: Data for this hospital based cross sectional study includes 130 pregnant women during the years 2022-2023. We have applied logistic regression and the decision tree method for predicting LBW in pregnancies. The performance of these predictive models has been assessed through receiving operating characteristic curve (ROC). Results: The findings revealed 38.5% prevalence of LBW in pregnancies. Factors such as age of mother, abortion, presence of co-morbidities, pregnancy complications, and gestational age have been identified as significant predictors ( Conclusions: Logistic have better accuracy than decision tree model. Decision tree excels at capturing patterns but may overfit and hence should be used with caution. This study highlighted the need of targeted policy implementation on maternal and childhood care to reduce the risk of LBW.
