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

Whole-cell biosensors can detect toxic aquatic heavy metals without requiring expensive instruments and trained operators, making them promising for on-site detection. However, most remain confined to laboratory research, with few developed into integrated devices, and face challenges in simultaneously quantifying two highly toxic heavy metals, cadmium and mercury. To address this, we developed a portable platform for the simultaneous detection of them in contaminated water. We first engineered
