Higher Diagnostic Accuracy of an AI Model for Colposcopy Compared With Conventional and Digital Colposcopic Evaluation.
Article in Journal of lower genital tract disease, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveColposcopy involves subjective visual assessment of cervical features that may indicate cervical dysplasia. Pattern recognition during colposcopy could be enhanced by artificial intelligence (AI). Using colposcopy images with precisely mapped multiple biopsy sites and corresponding histologic diagnoses, we developed an AI model, Cervix-AID-Net, to classify colposcopy images into low-grade disease [less than cervical intraepithelial neoplasia (CIN) grade 2] and high-grade disease (CIN grade 2 or above). The objective of this study was to compare the diagnostic performance of the Cervix-AID-Net model with the digital colposcope (DySIS) color map and colposcopists' interpretations of the cervix in identifying low-grade and high-grade disease.
methodsThe authors used 3,153 colposcopy images from 178 women, each with 4 biopsies, to train and validate the algorithm. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were calculated with 95% CIs.
resultsCervix-AID-Net achieved a diagnostic accuracy of 99.8% (95% CI: 99.6-99.9) in classifying colposcopy images into low-grade and high-grade categories. This was significantly higher than the DySIS color map accuracy of 58.8% (95% CI: 51.1-66.1) and the accuracy of the colposcopist's visual impression of the cervix (55.1%, 95% CI: 47.2%-62.5%).
conclusionThis first version of the Cervix-AID-Net demonstrated superior diagnostic accuracy compared with both the DySIS color map and colposcopists' visual assessment. The results need confirmation in a prospective clinical trial.
