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

Climate change is rapidly altering global glacier-fed rivers, with prevailing models assuming that water temperature increases dictate aquatic community succession. However, this thermal-centric paradigm struggles to explain biodiversity patterns within the extreme topographic and hydrologic gradients of the Third Pole. By analyzing macroinvertebrate assemblages across the Yarlung Tsangpo Basin, we show that hydrodynamic condition, rather than water temperature, primarily influences biodiversity and community assembly in these high-altitude alpine rivers. With hydrodynamic intensity indicated by specific stream power, taxa richness exhibits a universal unimodal response, consistently peaking under moderate hydrodynamic intensity (1 to 10 W m
