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

Water scarcity increasingly challenges the supply of sufficient quantities of safe water for human consumption. On-site water reuse systems can contribute to mitigating the effects of water scarcity by closing water cycles locally. However, broader adoption of on-site water reuse is constrained by the high cost of water quality monitoring. This work demonstrates the successful design and validation of low-cost chlorine amperometric sensors for long-term monitoring using Prussian blue-coated screen-printed carbon electrodes. The study is relevant for practice, as testing was conducted in a water reuse system treating real greywater and municipal wastewater. The sensors achieved a relatively stable sensitivity of 8.55 ± 1.19 μA/(ppm⋅cm
