Blue Lasing at Room Temperature Based on a Quasi-Bound State in the Continuum.
Article in Nano letters, 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
We demonstrate room-temperature lasing in the blue spectral range, 440 to 460 nm, where optical gain is provided by InGaN quantum wells coupled to quasi-bound states in the continuum hosted by a monolithic GaN-based subwavelength grating. A low-refractive-index nanoporous GaN layer obtained by electrochemical etching, placed beneath the structure, suppresses the coupling of the optical modes to the substrate. The gratings are designed by theoretical modeling and fabricated with sub-10 nm precision using e-beam lithography and dry etching. The presence of quasi-bound states in the continuum is confirmed by angle-resolved reflectivity and observation of a polarization vortex. The structures ensure a low threshold (0.16 mJ cm
