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

A great deal of attention has been directed to the toxicity, enrichment, and accumulation of urban river sediment pollution. To understand the spatial-temporal variation, ecological risk and source of nutrients, and heavy metals in sediments from the Weihe River, the concentrations of total nitrogen (TN), total phosphorus (TP), organic matter (OM), and 10 heavy metals (Cd, Sb, As, Co, Cu, Pb, Ni, Cr, Zn, and Mn) in sediments at 14 sampling sites along the river were investigated. The results showed that nutrients and heavy metals had an interannual decreasing trend, and that the high-value regions were concentrated in urban locations within the study area. Ecological risk assessment results showed that TN was between the security level (no toxic effect) and the lowest level (tolerable for organisms), TP was at the lowest level, and OM was within the security level, all mainly from external sources. The geoaccumulation index (I
