Structured light radial-view endoscope PROBE for IMAGING of colorectal tissue.
Article in Optics letters, 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
White-light endoscopy (WLE) is the current gold standard for endoscopic colorectal cancer screening. However, it lacks the ability to image subsurface colorectal tissue and provide functional assessments necessary for early-stage cancer identification and post-treatment evaluation. Spatial frequency domain imaging (SFDI) provides subsurface quantitative absorption and scattering properties, which can assist in distinguishing between different tissue types. In this paper, we present a new, to the best of our knowledge, compact, radial-view, dual-wavelength (740 nm and 850 nm) SFDI system and its accompanying reconstruction algorithm. The proposed system achieves real-time full circumferential imaging of the intestinal lumen and provides functional parameter estimation from a single snapshot. The performance of this endoscopic probe is evaluated using biomimetic microvascular phantoms, and its potential for biological tissue imaging is demonstrated through imaging of
