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

Surface sediments from the lower Coatzacoalcos River basin were analyzed to assess the distribution of potentially toxic elements (PTE: Cr, Cu, Pb, Zn), identify sites of ecotoxicological concern, and elucidate the sedimentary processes controlling their accumulation. The Coatzacoalcos River estuary (southern Gulf of Mexico) lies within one of Mexico's major industrial corridors, while small urban settlements and extensive agricultural areas impact the lower basin. Several sampling sites displayed concentrations of Cr (47.5-85.9 μg g
