Diagnostic value of real-time computer-aided detection for precancerous lesion during esophagogastroduodenoscopy: A meta-analysis.
Article in World journal of gastrointestinal surgery, 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
backgroundEarly detection of precancerous lesions is of vital importance for reducing the incidence and mortality of upper gastrointestinal (UGI) tract cancer. However, traditional endoscopy has certain limitations in detecting precancerous lesions. In contrast, real-time computer-aided detection (CAD) systems enhanced by artificial intelligence (AI) systems, although they may increase unnecessary medical procedures, can provide immediate feedback during examination, thereby improving the accuracy of lesion detection. This article aims to conduct a meta-analysis of the diagnostic performance of CAD systems in identifying precancerous lesions of UGI tract cancer during esophagogastroduodenoscopy (EGD), evaluate their potential clinical application value, and determine the direction for further research.
aimTo investigate the improvement of the efficiency of EGD examination by the real-time AI-enabled real-time CAD system (AI-CAD) system.
methodsPubMed, EMBASE, Web of Science and Cochrane Library databases were searched by two independent reviewers to retrieve literature with per-patient analysis with a deadline up until April 2025. A meta-analysis was performed with R Studio software (R4.5.0). A random-effects model was used and subgroup analysis was carried out to identify possible sources of heterogeneity.
resultsThe initial search identified 802 articles. According to the inclusion criteria, 2113 patients from 10 studies were included in this meta-analysis. The pooled accuracy difference, logarithmic difference of diagnostic odds ratios, sensitivity, specificity and the area under the summary receiver operating characteristic curve (area under the curve) of both AI group and endoscopist group for detecting precancerous lesion were 0.16 (95%CI: 0.12-0.20), -0.19 (95%CI: -0.75-0.37), 0.89 (95%CI: 0.85-0.92, AI group), 0.67 (95%CI: 0.63-0.71, endoscopist group), 0.89 (95%CI: 0.84-0.93, AI group), 0.77 (95%CI: 0.70-0.83, endoscopist group), 0.928 (95%CI: 0.841-0.948, AI group), 0.722 (95%CI: 0.677-0.821, endoscopist group), respectively.
conclusionThe present studies further provide evidence that the AI-CAD is a reliable endoscopic diagnostic tool that can be used to assist endoscopists in detection of precancerous lesions in the UGI tract. It may be introduced on a large scale for clinical application to enhance the accuracy of detecting precancerous lesions in the UGI tract.
