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
A potential impact of reactive halogens on climate and air quality is through oxidation of sulfur dioxide by hypohalous acids (HOX with X = Cl, Br, or I) to produce sulfate aerosols. This sulfate formation mechanism is typically not included in climate and air quality models, largely due to the limited observational evidence supporting its significance. In this study, we measured the oxygen isotopic composition of sulfate in aerosol particles as well as the concentrations of hypohalous acids during a field campaign in coastal Hong Kong. The oxygen isotopic signatures suggest that hypohalous acids account for more sulfate production than the traditional oxidant hydrogen peroxide (H
