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

Shortwave infrared (SWIR) photodetectors are essential for industrial, medical and security applications, but their adoption is limited by reliance on costly epitaxial semiconductors. Solution-processed organic and colloidal quantum dot (CQD) semiconductors offer a promising alternative, although their devices often suffer from high dark-current under reverse bias. We demonstrate an approach to precise work function modulation in SWIR photodetectors using conjugated polyelectrolytes with mixed counterions. This strategy achieves continuous work function tuning and interfacial defect passivation, significantly reducing dark current in solution-processed photodetectors. The optimized CQD photodetectors exhibit a dark-current density two orders of magnitude lower than that of conventional devices at -0.1 V bias (6.7 × 10
