Magnetic Electroluminescent response as a predictive indicator of operational lifetime in phosphorescent blue OLEDs.
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
Improving operational lifetime remains a major challenge for blue organic light-emitting diodes (OLEDs) harvesting triplet excitons. Achieving substantial lifetime enhancement requires analytical techniques that elucidate degradation mechanisms. Because conventional lifetime analysis involves destructive aging tests, developing non-invasive methods that correlate strongly with device longevity is highly desirable. Here, we show that the operational lifetime of blue phosphorescent OLEDs quantitatively correlates with the electroluminescence (EL) response under magnetic fields. This behavior is explained by a magneto-EL response function that reflects degradation-sensitive spin-pair kinetics under magnetic fields. A strong linear correlation (confidence > 95%) is identified between the magneto-EL response strength (f
