Determinants of low birth weight in newborns at a referral hospital in the western Nepal: an unmatched case-control study.
Article in BMC pediatrics, 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
backgroundLow Birth Weight, birth weight of less than 2,500 g regardless of gestational age, is a significant public health issue globally. This study investigates risk factors of LBW in the western Nepal, a region that has not been extensively studied.
methodsA hospital-based unmatched case-control study was conducted at Bheri Hospital in the western Nepal from July 2020 to June 2021. Three hundred mothers delivering live singleton babies, with 150 of them having newborns weighing less than 2,500 g (cases) and 150 of them weighing 2,500-4,000 g (controls) were selected using simple random sampling method. Data were collected through face-to-face interviews using structured questionnaire and review of hospital record reviews. Data were analyzed using STATA version 17. Multivariable logistic regression was performed to analyze the association, and adjusted odds ratio with 95% confidence interval and P-value < 0.05 were considered to be statistically significant.
resultsMothers with a monthly income above Nepali Rupees15,000 had lower odds of having LBW infants (aOR: 0.2, 95% CI: 0.1-0.3). Lack of support from husbands and mothers-in-law during pregnancy significantly increased the odds of LBW, (aOR: 3.9, 95% CI: 1.2-12.3; aOR: 9.5, 95% CI: 4.6-19.5, rspectively). Maternal smoking during pregnancy also increased the odds of LBW significantly (aOR: 8.9, 95% CI: 1.9-40.2). Intended pregnancy was protective, reducing the odds of LBW (aOR: 0.2, 95% CI: 0.1-0.3). Women with a history of delivering LBW babies had a higher risk of recurrence (aOR: 12.2, 95% CI: 1.5-98.7), and those with a recent abortion exhibited increased odds of LBW (aOR: 5.6, 95% CI: 1.8-17.5). Attending four or more ANC visits and receiving nutritional counseling significantly lowered the odds of LBW (aOR: 0.2, 95% CI: 0.07-0.7 and aOR: 0.2, 95% CI: 0.1-0.4, respectively). Weight gain of 7 kg. or more during pregnancy also reduced LBW risk (aOR: 0.1, 95% CI: 0.01-0.14), whereas preterm birth increased the odds of LBW (aOR: 9.5, 95% CI: 4.5-20.2).
conclusionsInterventions to reduce LBW should address these modifiable risk factors, emphasizing maternal nutrition, promoting ANC coverage, integrating routine nutritional counselling into ANC services, smoking cessation and promoting family support in daily activities during pregnancy.
