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

Agricultural watersheds are undergoing rapid rural-urban transitions, yet the relative contributions of diffuse agricultural runoff versus rural domestic and point sources to organophosphate esters (OPEs) pollution remain poorly understood. This study investigated the occurrence, spatiotemporal distribution, and potential risks of 17 legacy and emerging OPEs in the Dalongdong River, China. Combined non-target and target analyses revealed mean OPE concentrations of 111.94 ng/L in water and 8.76 ng/g in sediments. Spatially, total OPE concentrations increased progressively from upstream to downstream, with pronounced hotspots downstream of townships and near wastewater treatment facilities, indicating that rural domestic effluents and urban runoff, alongside agricultural activities, are critical contributors to OPE pollution in this watershed. Seasonally, concentrations of six legacy OPEs were significantly higher during the wet season. Furthermore, high-throughput phenotypic screening using
