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

Small-molecule phosphorescent materials feature high chemical purity and tailorable luminescence, yet aggregation-caused quenching (ACQ) and poor thermal stability remain critical bottlenecks. Herein, we designed and synthesized a series of carbazole-based derivatives (K-CN, K-Br₂, K-Cl, K-Br), these compounds bear heavy-atom substituents (-Br, -Cl) and rigid skeletons to enhance spin-orbit coupling for efficient intersystem crossing. The rigid carbazole backbone suppresses non - radiative decay, and the optimized molecular structure avoids quenching. Exhibiting relatively extended phosphorescent afterglow durations (0.6-3 s) and long phosphorescence lifetimes (τ
