Objective Assessment of Visibility of Colorectal Lesions Using Eye Tracking for New Image-Enhanced Endoscopy Observation.
Article in Journal of gastroenterology and hepatology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
BACKGROUND AND
aimThis study aimed to objectively evaluate colorectal lesion visibility using white-light imaging (WLI), narrow-band imaging (NBI), and texture and color enhancement imaging (TXI) with an eye tracking system.
methodsTwelve endoscopists assessed 120 images of 30 colorectal lesions (29 adenomas, one sessile serrated lesion) captured using WLI, NBI, TXI mode-1, and TXI mode-2. Eye movements were recorded to analyze the lesion detection ability and time taken. The miss rate (calculated as the ratio of missed lesions from 360 images) and detection time (defined as the time from displaying the image to the start of gaze on lesions) were compared among the four modalities.
resultsThe miss rates of WLI, NBI, TXI mode-1, and TXI mode-2 were 16.4%, 6.4%, 11.7%, and 16.7%, respectively. The miss rate of NBI was significantly lower than those of WLI and TXI mode-2 (p < 0.001). The detection times (median [interquartile range]) of WLI, NBI, TXI mode-1, and TXI mode-2 were 0.71 (0.43-1.37) s, 0.54 (0.34-0.89) s, 0.63 (0.44-1.13) s, and 0.64 (0.37-1.28) s, respectively. NBI had the shortest detection time among the four modalities (p < 0.001 compared with WLI and TXI mode-2; p = 0.005 compared with TXI mode-1).
conclusionsObjective assessment using the eye tracking system revealed that NBI provided the best colorectal lesion visibility, with the lowest miss rate and shortest detection time.
