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

The simple preparation of superhydrophilic membranes with good stability is of great significance for efficient oil-water separation. In this work, a polyvinylidene fluoride (PVDF) membrane modified with tannic acid (TA) and pectin (PT) was developed through immersion in TA/PT solutions, facilitating the formation of complexes via co-deposition. The optimized PVDF@TA/PT3 membrane exhibited superhydrophilicity/superoleophobicity. The membrane achieved remarkable separation efficiencies exceeding 98.3% and fluxes ranging from 71.3 to 156.3 L m
