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
Biomass burning aerosol (BBA) contributes significantly to the global aerosol burden, yet its chemical nature and ice nucleation activities (INAs) are unconstrained due to the heterogeneity in biomass sources and complex evolution of atmospheric aging processes. This study comprehensively investigates the chemical composition and INA of BBA generated through laboratory-controlled burns with different biomasses and burning conditions. Both freshly emitted and photochemically aged BBA produced from different processes exhibit distinct and reproducible chemical compositions. However, the INA of BBA shows substantial variability at mixed-phase cloud temperatures and cannot be predicted by the chemical variability of the enriched carbonaceous materials. This indicates the negligible role of carbonaceous materials in determining the INA of BBA. Using laboratory data, we further evaluate the impact of BBA on atmospheric ice nucleation using particulate matter mass concentration and particle equivalent spherical radius. The estimated ice nucleating particle (INP) concentrations contributed by laboratory-produced BBA are lower than those observed during BBA pollution in field studies. This discrepancy is likely attributed to co-lofted mineral particles during real-world biomass burning, such as ash or soil particles, rather than carbonaceous-rich particles from combustion. We encourage further research to quantify the contribution of mineral particles to the INP concentrations of BBA.
