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

Conventional infrared imaging systems rely heavily on external power supplies, limiting their applicability, flexibility, and portability. Here, we present a monolithically integrated photon-mapping near-infrared (780-900 nm) imager that operates in a self-driven mode, achieving a resolution of 5799 ppi and a frame rate of 18.5 kHz. The device vertically integrates multiple photovoltage-generating light-sensing units with a light-emitting unit in a cascaded configuration, enabling visible emission upon near-infrared excitation via internal carrier transfer. Its circuit-free architecture confers intrinsic flexibility and large-area scalability while remaining fully compatible with room-temperature operation. The system eliminates the need for pixel-level readout, thereby enabling spatial resolution beyond conventional pixel limits under optical excitation control. It further supports high-speed imaging governed by the transit dynamics of photogenerated carriers. In addition, its self-driven characteristic ensures inherently low background noise, enhancing the signal-to-background ratio and improving imaging quality. This work introduces a simplified, energy-efficient approach to infrared visualization.
