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

Although pervaporation (PV) desalination is a promising solution to global freshwater scarcity, membranes suffer from unstable separation performance. This study utilized resource recycling to prepare a porous ceramic membrane using solid waste fly ash as raw material, which was then combined with polyimide (PI) to produce a high-performance composite membrane (abbreviated to as PI/ceramic membrane). In this composite membrane, the ceramic membrane provides mechanical support and promotes rapid water passage, while the PI layer intercepts hydrated salt ions through size screening and electronic repulsion. Through their synergistic action, the composite membrane can preferentially adsorb and diffuse water molecules while retaining. Results indicate in addition to a retention efficiency of nearly 99.9%, the PI/ceramic membranes achieved a permeability of 10.88 L (m
