Knowledge about the health impact of indoor air pollution and associated factors among mothers in northeastern Ethiopia: a community-based cross-sectional study.
Article in BMJ open, 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
objectiveThis study was designed to determine the level of knowledge about the health impact of indoor air pollution (IAP) and associated factors among mothers in northeastern Ethiopia.
designA community-based cross-sectional study was carried out from May to June 2024. A systematic sampling technique was used to select the study participants. Using a pretested and structured questionnaire, data were gathered through interviews. The collected data were entered into EpiData V.4.6 and SPSS V.25 was used for the analysis. The adjusted OR with a 95% CI and the significance of associations at p
settingThe study was conducted in northeastern Ethiopia.
participantsA total of 401 mothers participated in this study. OUTCOME MEASURES: The primary outcome is the prevalence of good knowledge about the health impact of IAP.
resultsWith a response rate of 95%, 401 mothers in all completed the survey. Of the participants, 205 (51.1%) were aged ≤31 years. In this study, 46.4% (95% CI 41.6 to 51.4) of the 401 participants had good knowledge about the health impact of IAP. Higher educational level (adjusted OR (AOR): 4.4, 95% CI 2.38 to 8.14), higher income (AOR: 1.88, 95% CI 1.15 to 3.06) and receiving training (AOR: 2.72, 95% CI 1.14 to 6.46) were factors associated with having good knowledge.
conclusionThis study concluded that less than half of the mothers had good knowledge about the health impact of IAP. The findings of this study highlight the critical need for policymakers to address the inadequate understanding among mothers of the health impact of IAP. Thus, the health education programme on IAP should be strengthened through effective community engagement.
