Factors Influencing Chronic Pain After Hysterectomy for Uterine Fibroids: Development and Validation of a Nomogram Prediction Model.

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
Objective: To develop and validate a nomogram prediction model for chronic pain after hysterectomy for uterine fibroids. Methods: A retrospective study was conducted on 315 patients who visited our hospital from January 2022 to July 2024. The patients were stochastically assigned into training dataset (n=220) and validation dataset (n=95) in a 7:3 ratio. The training dataset was assigned into non chronic pain group (n=164) and chronic pain group (n=56) based on whether chronic pain persists for more than 3 months after surgery. Multivariate logistic regression was used to screen for predictive factors. R software was used to construct nomogram models. The calibration curve was used to evaluate the calibration degree of nomogram. ROC curve was used to evaluate the discrimination of nomogram. The clinical decision curve analysis was used to discuss and evaluate the net profit of the nomogram. Results: Preoperative pain, history of abdominal or pelvic surgery, endometriosis, anxiety, and high Pain Catastrophic Scale (PCS) score were independent risk factors for chronic pain after hysterectomy for uterine fibroids (P<0.05). The nomogram model showed high predictive performance in both the training and validation datasets, and the calibration curves showed good consistency and calibration degree, the Hosmer-Lemeshow test showed Conclusion: The nomogram developed in this study accurately predicts the risk of chronic pain after hysterectomy for uterine fibroids, which is beneficial for preoperative planning and patient consultation.
