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

This study combines experimental and theoretical methods to explore the photochemical stability of progestins in a climate-sensitive model system for urban reservoirs worldwide, with a focus on the Guarapiranga Reservoir in São Paulo, Brazil. The target contaminants were levonorgestrel (LNG) and gestodene (GES), synthetic progestins used in contraceptive methods. Photoinduced reaction kinetics showed that LNG's indirect photolysis is affected by triplet excited states of chromophoric dissolved organic matter (3CDOM*), hydroxyl radicals (HO·), and singlet oxygen (
