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

Short-wave infrared (SWIR) technologies are vital for optical communication, all-weather imaging, and advanced spectroscopy. Using a single diode for light detection and emission can reduce device footprints, lower cost and enable fast, bidirectional communication. However, dual detection/emission operation often involves incompatible choices of material and stack design, which result in devices with inferior performance. Here, we introduce a bifunctional PbS QD diode stack that achieves, for the first time, nanosecond-fast photodetection and emission in a single SWIR device. Using thin active layers with high charge-carrier mobility and compact geometries, we demonstrate a record 2 ns response in photodiode (QDPD) mode and 11.7 ns rise time/6.5 ns fall time in light-emitting diode (QDLED) mode. This high-speed operation is combined with a 49% external quantum efficiency (EQE) and 2.6 × 10
