Minute-scale red phosphorescence in carbon nanodots.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Red phosphorescent materials with long-lived triplet excitons are highly desirable for optoelectronic and bio-related applications but remain limited by short emission lifetime. Here we show ultralong red phosphorescent carbon nanodots, which exhibit minute-scale phosphorescence. Through combining excited-state engineering assisted by machine learning optimization, the obtained red carbon nanodots achieve the phosphorescence lifetime of 353 second, with emission persistence exceeding 4000 second. Spectroscopic analysis reveals the coexistence of a fast radiative transition channel from
