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

The benign defect nature of iodide perovskites has gained strong momentum in understanding and application in perovskite devices; however, the understanding of defects in bromide perovskites remains elusive. Here we demonstrate that the biasing of lead bromide perovskite crystals, which has been broadly deemed as detrimental to device performance, can efficiently repair bulk point defects in them. The biasing results in a significant bromide-vacancy reduction, starting from the cathode side and progressing to the anode side across the whole crystal. The vacancies can diffuse back after several weeks of storage. By introducing bromine in crystal growth, we permanently reduce the bromide-vacancy concentration by ~1,000 times, enhancing charge transport and stability in formamidinium lead bromide crystals. The optimized formamidinium lead bromide detector exhibited a very high detection performance including an energy resolution of 0.7% under
