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

Rapid on-site detection of heavy metal ions is important for food and water safety, while traditional electrochemical stripping voltammetry is limited by its time-consuming preconcentration step. Herein, an integrated photo-assisted electrochemical potentiostat, PAEcStat, was developed for the rapid preconcentration-free detection of heavy metal ions. The system integrates a 20 W LED driver with closed-loop light-intensity regulation and a low-noise electrochemical analog front-end for differential pulse voltammetry. The illumination intensity can be regulated from 1000 to 19,000 lux at a distance of 10 cm with an error within ±100 lux. The analog front-end provides a current detection range of 10 nA to 4 mA, with excellent linearity (R
