Toward automatic and reliable evaluation of human gastric motility using magnetically controlled capsule endoscope and deep learning.
Article in Scientific reports, 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
In this paper, we develop a combination of algorithms, including camera motion detector (CMD), deep learning models, class activation mapping (CAM), and periodical feature detector for the purpose of evaluating human gastric motility by detecting the presence of gastric peristalsis and measuring the period of gastric peristalsis. Moreover, we use visual interpretations provided by CAM to improve the sensitivity of the detection results. We evaluate the performance of detecting peristalsis and measuring period by calculating accuracy, F1, and area under curve (AUC) scores. Also, we evaluate the performance of the periodical feature detector using the error rate. We perform extensive experiments on the magnetically controlled capsule endoscope (MCCE) dataset with more than 100,000 frames (100,055 specifically). We have achieved high accuracy (0.8882), F1 (0.8192), and AUC scores (0.9400) for detecting human gastric peristalsis, and low error rate (8.36%) in measuring peristalsis periods from the clinical dataset. The proposed combination of algorithms has demonstrated the feasibility of assisting in the evaluation of human gastric motility.
