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
introductionThe relationship between household air pollution from solid fuel use and hypertension remains uncertain, especially in low- and middle-income countries.
aimWe aimed to examine the association between use of solid fuels in households and hypertension in a large, nationally representative sample from Peru.
methodsWe conducted a cross-sectional analysis of 137,012 adults using data from the 2020-2024 Demographic and Family Health Survey. Cooking fuel exposure was categorized as no exposure (clean fuels), moderate exposure (solid fuel with chimney), or high exposure (solid fuel without chimney). The primary outcome was hypertension, defined as a mean systolic/diastolic blood pressure ≥140/90 mmHg or self-reported diagnosis. The secondary outcomes were systolic and diastolic blood pressure. Modified Poisson and linear regression were used to estimate adjusted prevalence ratios (aPRs) and beta coefficients with their 95% confidence intervals (CIs), respectively.
resultsIn the adjusted analysis, high exposure to solid fuel was modestly associated with a higher prevalence of hypertension (aPR 1.08, 95% CI 1.02-1.14) compared with clean fuel use. Moderate exposure showed no significant association (aPR 1.01, 95% CI 0.95-1.08). Stronger associations were observed in women (aPR 1.14, 95% CI 1.05-1.23) and urban residents (aPR 1.14, 95% CI 1.05-1.24). High exposure was also associated with small but significant increases in systolic (β = 0.65, 95% CI 0.20 to 1.1 mmHg) and diastolic (β = 0.54, 95% CI 0.26 to 0.81 mmHg) blood pressure.
conclusionHigh-intensity exposure to solid cooking fuels, particularly without adequate ventilation, was modestly associated with hypertension and small increases in systolic/diastolic blood pressure. These findings emphasize the importance of ensuring access to clean energy and enhancing kitchen ventilation, particularly among women and urban populations.
