Sequential RGB color imaging with a millimeter-scale monochrome camera with a rolling shutter.
Article in Applied optics, 2023. 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
Applications are growing for ultracompact millimeter-scale cameras. For color images, these sensors commonly utilize a Bayer mask, which can negatively and perceptibly have an impact on image resolution and quality, especially for low pixel-count submillimeter sensors. To alleviate this, we built a time-multiplexed RGB LED illumination system synchronized to the rolling shutter of a monochrome camera. The sequential images are processed and displayed as near real-time color video. Experimental comparison with an identical sensor with a Bayer color mask showed significant improvement in the MTF curves and to perceived image clarity. Trade-offs with respect to system complexity and color motion artifacts are discussed.
