Article in Science advances, 2025. 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
Metal halide perovskites offer exceptional sensitivity for direct x-ray detection through direct current (DC) signals, but the DC bias-induced ion migration poses substantial challenges to their signal consistency and operational stability. In this work, we propose a capacitance signal-based imaging strategy that uses an alternating current (AC) bias to suppress ion migration and eliminate nonlinear responses. A quantitative correlation between capacitance changes and x-ray dose rate is established, enabling stable, high-resolution imaging. Using this method, we achieve three-dimensional internal structure reconstruction with a simple single-pixel detector. This approach overcomes intrinsic material limitations and enhances signal reliability, providing a promising pathway toward the commercialization of low-cost, high-performance perovskite-based x-ray imaging and computed tomography systems.
