Estimation of concentration and risk assessment of PAHs in urban water resources due to cigarette butt littering.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Filtered cigarettes are now the dominant form of tobacco consumption worldwide, resulting in the production of 5 trillion/year cigarette butts as hazardous waste. Most cigarette butts are littered by smokers, and the trapped pollutants quickly leak into the environment. In this study, the density of littered cigarette butts in urban environment was interpreted by Cigarette Butt Pollution Index and the ecological risk and carcinogenic risk due to water pollution caused by leaked PAHs from the littered cigarette butts were assessed. The results showed that the density of littered cigarette butts in the most polluted location was 0.61 butts/m
