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 built-in electric field (BIEF) is a fundamental driving force governing the separation, transfer, and lifetime of photogenerated charge carriers, thereby dictating the activity of photocatalysts. Herein, a local p-π conjugation regulation strategy was developed to tailor the BIEF in covalent organic frameworks (COFs) as advanced photocatalysts. Three COFs of NKU-191, NKU-191-OH, and NKU-191-OMe, featuring robust acid-base resistance, high stability, and high specific surface area, were synthesized via Schiff base reactions under mild conditions. Without altering their intrinsic backbone structure, the photocatalytic hydrogen evolution activity was enhanced from 4.8 mmol g
