Determinants of low birth weight and effect of indoor air pollution on birth weight: A case-control study in a tertiary care centre of Hubballi, Karnataka.

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: The majority of all low birth weight (LBW) babies are born in developing countries, and half of the population in developing nations use solid fuels as their primary source of energy for cooking. An association between household use of solid biomass fuels and reduced newborn weight has been found in several countries. India has a high prevalence of LBW babies, and 88% of the population use solid fuels for cooking. Objectives: To evaluate the determinants of low birth weight and to assess the effect of exposure of pregnant women to indoor air pollution on the birth weight of newborns. Methodology: A case-control study was conducted on singleton newborn babies of KIMS hospital, Hubballi. A structured pretested validated questionnaire was administered to 146 participants including 73 cases (new born babies with birth weight <2.5 kg) and 73 controls (new born babies with birth weight ≥2.5k g). The questionnaire comprised of sociodemographic characteristics, obstetric history, medical illnesses, and the current pregnancy with its outcomes and indoor air pollution. Results: The study found a significant association between low birth weight and a history of low birth weight, no intake of albendazole tablets, hemoglobin levels during pregnancy, exposure to smoke from mosquito repellent coils during pregnancy, burning of volatile liquids at home, and duration of exposure to indoor air pollutants during pregnancy. Conclusion: Indoor air pollution significantly affects the baby's birth weight. Appropriate antenatal care and health education to overcome indoor air pollution can significantly improve the birth weight of the baby.
