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

Sludge, a rapidly accumulating by-product of wastewater treatment worldwide, holds great potential as an ideal coal substitute following dehydration and drying. Here, we present a solar-powered heavy metal trap (SPHT) designed for sludge drying and concurrent electricity generation, validated using a PPy-coated super hydrophilic wood (PPy-H-Wood). The SPHT in this work uniquely integrates sludge drying, heavy metal removal, and electricity generation characteristics. The indoor experiments demonstrate a rapid decrease in sludge water content from 90 % to 31 %, accompanied by an impressive 94 % reduction in free heavy metal content achieved through synergistic adsorption and evaporation. Harnessing the hydrovoltaic effect, the SPHT can generate an initial potential of 0.10 V. By monitoring this hydrovoltaic potential, the sludge drying process can be self-detected. Furthermore, we have constructed a 20 m
