Exploring the association between indoor air pollution (IAP) and anaemia among pregnant women in India.
Article in PloS one, 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
backgroundAnaemia during pregnancy in India persists despite policy attention and nutritional interventions. While its primary determinants are well-recognized, the association between indoor air pollution (IAP) and anaemia among pregnant women in India remains conspicuously under-explored.
methodsThis study examines the relationship between exposure to IAP and anaemia among pregnant women, using the National Family Health Survey (NFHS-5, 2019-21), with an analytical sample of 25,579 respondents. Descriptive statistics, chi-square tests, and multivariable logistic regression were used to assess the association between IAP exposure and anaemia, while accounting for socio-demographic, health, and behavioural characteristics.
resultsIAP was significantly associated with higher odds of anaemia (COR: 1.43, 95% CI: 1.36-1.51). Pregnant women who were younger, had lower levels of education, resided in rural areas, belonged to scheduled tribe communities, and poor wealth index household were more likely to be anaemic.
conclusionThese findings suggest the need to integrate household energy transitions and indoor air quality improvements into maternal anaemia reduction strategies.
