High-Risk Clinical Characteristics and Risk Model for Unexpected Cervical Cancer Diagnosed After Surgery in Patients with LSIL/HSIL Biopsy.

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: Women with colposcopy-directed biopsy results of low-grade or high-grade squamous intraepithelial lesion (LSIL/HSIL) who are subsequently found to have cervical cancer after surgery likely represent missed preoperative malignancy. This study aims to identify risk factors associated with these missed diagnoses and to develop a preoperative risk prediction model. Methods: Patients with LSIL/HSIL on colposcopy-directed biopsy who underwent cervical conization or hysterectomy at a single center were retrospectively included. Postoperative cervical cancer was the adverse outcome. Baseline characteristics were compared using chi-square tests. Predictors were identified by univariate and multivariable logistic regression to build a logistic regression model. Internal validation applied machine learning with five-fold cross-validation. Performance was evaluated by receiver operating characteristic (ROC) curve (AUC) and accuracy, with discrimination, calibration, and clinical utility assessed using ROC curves, calibration plots, and decision curve analysis (DCA). Results: A total of 1271 patients were included, and 79 were diagnosed with cervical cancer after surgery. Risk factors significantly associated with postoperative cervical cancer diagnosis included age (OR, 1.0; 95% CI, 1.0-1.0, p=0.045), gravidity (OR, 1.2; 95% CI, 1.1-1.3, p <0.001), human papillomavirus 16 or 18 infection (OR, 2.6; 95% CI, 1.4-4.6, p=0.002), colposcope biopsy site numbers ≥4 (OR, 0.2; 95% CI, 0.1-0.3, p <0.001), ThinPrep Cytologic Test indicates high-grade squamous intraepithelial lesion (OR, 3.1; 95% CI, 1.1-8.5, p=0.028), and neutrophil-to-lymphocyte ratio (OR, 1.1; 95% CI, 1.0-1.3, p=0.015). In five-fold cross-validation, the machine learning algorithms yielded an AUC of 0.72-0.81 and an accuracy of 0.93-0.94 for the model. ROC curves, calibration curves, and DCA analysis demonstrate the model's excellent predictive capability and performance. Conclusion: This study developed and internally validated a clinical prediction model to estimate the preoperative risk of occult cervical cancer in patients with LSIL/HSIL on colposcopy-directed biopsy. This model may support risk-stratified surgical decision-making and help reduce missed diagnoses.
