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

Ionic polymeric carbon nitrides, poly(heptazine imides) (PHIs), have emerged as promising photocatalysts, yet the relationship between their structure, exciton dynamics, and activity has remained elusive so far. Here, a direct link is established between photocatalytic activity, spectroscopic properties, and theoretical analysis of structural effects on exciton behavior in water-soluble PHIs with different cations. Using steady-state and time-resolved emission spectroscopy alongside ultrafast transient absorption spectroscopy performed in the absence and presence of hole and electron quenchers, two distinct excitonic relaxation pathways are uncovered: sub-100 ps decay dominated by exciton recombination and shallow-trap states, and sub-ns dynamics associated with deep-trap assisted recombination. Notably, ethanol accelerated the sub-100 ps decay via hole quenching, while the deep traps are unaffected by ethanol. The spectroscopic results show that the photocatalytic activity in H
