Identification of Risk Factors and Development of a Prediction Model for Recovery Room Delirium Following Transurethral Resection of the Prostate.

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
Purpose: To identify independent risk factors for recovery room delirium (RRD) in patients undergoing transurethral resection of the prostate (TURP) and to develop a predictive model for early identification of high-risk patients. Patients and Methods: We retrospectively reviewed 1166 adult patients who underwent TURP under general anesthesia between January 2020 and December 2024. RRD was assessed using the 3-minute Diagnostic Interview for CAM-defined Delirium (3D-CAM). Patients were randomly assigned to the training set (n = 816) and the validation set (n = 350). Independent risk factors were identified by multivariate logistic regression, and a nomogram was constructed. Model performance was evaluated by the area under the receiver operating characteristic curve (AUC), calibration curve, and decision curve analysis (DCA). Results: The incidence of RRD was 19.5% in the training set and 20% in the validation set. Multivariable logistic regression identified older age, higher ASA physical status classification, preoperative hypoalbuminemia, intraoperative hypothermia, and intraoperative hypotension as independent predictors associated with an increased risk of RRD. Based on these predictors, a nomogram was established. The model demonstrated good discrimination, with an AUC of 0.841 (95% CI, 0.806-0.876) in the training cohort and 0.858 (95% CI, 0.810-0.906) in the validation cohort. Calibration analysis showed good agreement between the predicted and observed probabilities, and decision curve analysis demonstrated favorable clinical utility across a wide range of threshold probabilities. Conclusion: The RRD prediction model incorporating age, ASA classification, preoperative hypoalbuminemia, intraoperative hypothermia, and hypotension demonstrated promising discriminatory ability and calibration in this single-center cohort. However, prospective external validation is required before widespread clinical implementation.
