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 registryThe 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.

6 · The paper itselfAbstract
Polycyclic aromatic hydrocarbons with multiple-resonance (MR) effect are emerging as leading candidates for wide-color-gamut displays. However, it remains a significant challenge to red-shift their emissions to long wavelengths without sacrificing the spectral full width at half maximum (FWHM). Herein, a synergistic strategy of aromaticity localization and tetraboron extension is newly proposed, in which a B‒N covalent-bond-fused MR core is fused with 5,10-dihydro-5,10-diphenylphenazine (DPPA) to afford two yellow-emitting narrowband tetraboron emitters. By integrating multiple local B-π-B motifs into a rigid square-like tetraboron MR framework, DPA-4B and DMAC-4B achieve a pronounced red shift from violet-blue DPA-1B to yellow emission. The antiaromatic N
