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

Multiwavelength laser sources are indispensable in the development of quantum information, laser lighting, and laser display technologies. However, conventional multiwavelength lasers are costly, cumbersome, and intricate, limiting their adaptability across various applications. To overcome these challenges, we propose an integrated multiwavelength laser source based on solution-processed colloidal quantum wells (CQWs). Through precise control over size, elemental doping, and the design of heterostructures, we have engineered CQWs that exhibit ultralow stimulated emission thresholds across red, orange, yellow, and green wavelengths. CQW-based multiwavelength laser source delivers single-mode lasing with narrow line widths below 50 pm. Importantly, the laser structure is optimized via optical fiber coupling strategies, eliminating the need for complex micromanipulation procedures. Furthermore, we provide a preliminary demonstration of the applications of CQW-optical fiber lasers in automobile exhaust sensing, confirming their great promise for further development. These impressive specifications for colloidal semiconductor lasers highlight their strong potential as a powerful platform for next-generation visible light laser technologies.
