1 · What the graph read from it

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.

2 · The registry

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

Household air pollution from biomass fuel combustion affects approximately 36% of the world's population and is associated with negative health, environmental, economic, and social impacts. Although randomized controlled trials (RCTs) designed to reduce household air pollution have largely focused on health and environmental outcomes, evidence regarding their impact on quality of life (QOL) and household financial status remains limited. We conducted an RCT to evaluate the impact of a liquefied petroleum gas (LPG) intervention on health outcomes among 180 women aged 25-64 years who were the primary cooks in their households. We randomly assigned half of the participants to receive an LPG stove, continuous fuel supply for 12 months, and behavioral reinforcement. The other half continued usual cooking practices. We assessed QOL as a secondary outcome using the Short Form 36 Version 2 (SF-36-v2) and the EuroQol-5D-3L (EQ-5D). We also asked participants to report any perceived change in their household financial status 12 months after randomization. A total of 179 women (mean [±SD] age 48.3 ± 10.1 years) completed the surveys. In intention-to-treat analyses, participants in the intervention arm had similar SF-36 scores at 12 months compared with controls (mental component score: 48.3 vs. 50.9,
