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 registryThe 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.

6 · The paper itselfAbstract
Benzo[a]pyrene (BaP) is widely used as a model compound for studying the heterogeneous oxidation of particle-borne polycyclic aromatic hydrocarbons (PAHs), yet its decay kinetics under real atmospheric environments remain poorly constrained. Here, we present the first day-by-day determination of nighttime decay rates of particulate BaP using bihourly measurements in urban Shanghai. Two decay patterns were observed: incomplete decay with substantial remaining BaP, and complete decay with little residual BaP. Across 88 nights, decay rates averaged 0.21 ± 0.15 h
