Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
The development of ultra-high-definition organic light-emitting diodes (OLEDs) displays requires efficient and narrowband blue emission. Nevertheless, binary host-guest doped narrowband blue OLEDs still face significant challenges in simultaneously realizing high efficiency and negligible roll-off. Herein, a molecular construction strategy through the synergistic interplay between π-conjugation extension and functional complementarity fusion is proposed by incorporating a rigid boron-oxygen (BO) framework with carbazole building blocks. The constructed compounds exhibit increased triplet exciton recycling capability, high excited-state energy levels, and improved charge transporting features, showcasing significant potential as host matrices for blue devices. The sensitizer-free OLEDs achieve the narrowband blue emission with a CIEy value lower than 0.15, a maximum external quantum efficiency of 41.2%, and the suppressed efficiency roll-off at high luminance due to efficient energy transfer to blue guest emitters and elevated horizontal dipole orientation. This work strategically demonstrates a balance between high efficiency and reduced efficiency roll-off in binary narrowband blue OLEDs, representing a substantial advancement in blue electroluminescent technology.
