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 registryThe 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.

6 · The paper itselfAbstract
Rational integration of strong photosensitive moieties and multiple active sites into high performance photocatalysts is challenging due to uncontrollable intercrossing charge transfer. Herein, a series of imine-bonded two- and three-motif covalent organic frameworks, USTB-65∼USTB-68, have been studied, which feature triphenylamine unit as electron-donor (D) together with benzothiadiazole and/or 2,4,6-triphenyl-1,3,5-triazine moieties as electron-acceptor (A). Introduction of benzene rings as π-bridge into the D-A-A lattice of three-motif USTB-65 affords D-A-π-A USTB-66, leading to more facile exciton dissociation and efficient step-wise charge transfer among three motifs as revealed by various photophysical investigations and theoretical calculations. This, in combination with strong light absorption and multiple photocatalytic sites, results in the outstanding activity of USTB-66 in H
