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

Two-dimensional (2D) polymers have recently emerged as a hot topic in photocatalysis because of their rich active sites, tunable topology, and electronic structures. However, they typically suffer from severe photogenerated charge recombination, which hinders further elevation in photocatalytic performance. Here, we develop a method of direct condensation between amino and carboxyl groups to prepare a series of 2D polyaramids (2DPAs). Compared with the conventional fully π-conjugated 2D polyimide (2DPI), one of the 2DPAs (denoted as 2DPA-PPA) has an almost identical molecular skeleton but features a close yet spatially separated HOMO and LUMO distribution (the recombination rate is below 1/3 that for 2DPI, and the charge separation state lifetime is 5.5 times as long). Consequently, the rate of photocatalytic O
