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

Developing high photochromic contrast photoswitches in the solid state remains a significant challenge in organic smart materials. We here provide an oxygen-acceptor strategy for constructing an excited-state intramolecular proton transfer (ESIPT)-inspired organic photoswitch, namely tpmSA. By introducing a bulky triphenylmethane into the salicylaldehyde skeleton, tpmSA can achieve photochromic behavior in the solid state. Upon exposure to ultraviolet (UV) light, tpmSA displays distinct color variation from white to yellow, yielding a high photochromic contrast (ΔE*
