Development and validation of a machine learning-based prediction model for urinary calculi recurrence.

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
Urinary calculi recurrence substantially exacerbates healthcare resource consumption and socioeconomic burdens, yet the underlying mechanisms remain unclear. This study aimed to identify critical risk factors for calculi recurrence, develop a machine learning (ML) algorithm-based predictive model, and evaluate its predictive performance. This retrospective cohort study analyzed 1,146 urinary calculi patients treated at the Department of Urology, the Second Affiliated Hospital of Zhengzhou University (2019–2024). Key risk factors were identified using least absolute shrinkage and selection operator (LASSO) regression combined with multivariate logistic regression, and a binary predictive model for recurrence risk was developed. Model performance was validated via the area under the curve (AUC), with SHAP (Shapley Additive Explanations) values applied to interpret predictions. This study ultimately included 708 patients. The Random Forest model was selected as the optimal algorithm, demonstrating the following performance in the validation set: AUC 0.741 (95% CI: 0.664–0.818), sensitivity 0.552 (0.426–0.674), specificity 0.828 (0.756–0.885), positive predictive value 0.597 (0.464–0.719), negative predictive value 0.800 (0.727–0.861), F1-score 0.574, and Brier score 0.186, indicating satisfactory model calibration. SHAP feature attribution analysis identified the top four factors associated with recurrence: 24-hour urinary calcium excretion, hypertension status, serum creatinine level, and 24-hour urinary oxalate excretion. This study innovatively integrated metabolic data with imaging characteristics to establish a machine learning-based predictive model for quantitative recurrence risk assessment in urinary calculi. The integration of key metabolic parameters with imaging features has enhanced the predictive performance of the model, providing an evidence-based decision-making tool for personalized metabolic intervention and recurrent stone prevention strategies.
