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

The Los Angeles (LA) wildland-urban interface (WUI) fires of January 2025, are among the most destructive natural disasters in U.S. history, generating complex emission profiles that remain insufficiently characterized. An intensive field sampling campaign was conducted during the active burn period to collect and characterize the complex physicochemical properties of size-segregated particulate matter (WUIF-PM), vapor-phase compounds (WUIF-VOC), and ash (WUIF ash). While regulatory air quality indices remained within moderate categories during the sampling period, chemical analyses revealed substantial enrichment of hazardous species relative to urban background and biomass-only wildfire conditions. Oxygenated and highly toxic polycyclic aromatic hydrocarbons (OPAHs) were found in ultrafine WUIF-PM
