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

Highly stable and efficient organic light-emitting diodes (OLEDs) with high color purity are critical for ultrahigh-definition display applications. However, achieving these characteristics is hindered by the emitter bandwidth and device stability. Herein, we present the design of tetradentate green Pt(II) emitters with a rigid three-dimensional structure via extended π-conjugation and bulky substituents. This molecular engineering approach effectively suppresses excited-state geometric distortion, resulting in a small full width at half-maximum (FWHM) of 16.4 nanometers in toluene. When the emitters were used in a microcavity-enhanced top-emitting device, the FWHM was further reduced to 14.8 nanometers by controlling constructive and destructive interferences. The top-emitting device showed a Broadcast Service Television 2020 (BT.2020) green color [Commission Internationale de l'Éclairage (CIE): 0.22, 0.75] and a high current efficiency of up to 174 candelas per ampere. Most notably, the device exhibited a record-breaking operational stability, exceeding that of the commercial LED/OLED/MicroLED (micro-light-emitting diode) standard, achieving an unprecedented lifetime to 90% of the initial luminance of 540,100 hours at 1000 candelas per square meter.
