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 Tongyang River Basin, a rural tributary of Lake Chaohu with numerous polders, has been subjected to intensive anthropogenic degradation, leading to the implementation of a series of in situ nutrient reduction projects during 2023-2024. Based on spring samplings at 22 sites before (2021 and 2022) and after (2025) the projects, we characterized phytoplankton community structure and evaluated ecological health using the phytoplankton community index (Q
