Clinical analysis of uterine parameters evaluated by preoperative magnetic resonance imaging in patients treated by hysteroscopic approach with previous cesarean scar defect-related abnormal uterine bleeding: a retrospective cohort study.

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: As the cesarean delivery rate continues to rise globally, the treatment of previous cesarean scar defects (PCSD) remains challenging. This study aimed to analyze the variables that may influence the clinical cure rate of patients with PCSD-related abnormal uterine bleeding (AUB) as determined by preoperative magnetic resonance imaging (MRI) following hysteroscopic therapy. Methods: Women who underwent hysteroscopic surgery for PCSD-related AUB at the Gynecology Department of Third Xiangya Hospital of Central South University from 2018 to 2022 were recruited to this retrospective cohort investigation. A total of 147 patients were enrolled in this study and underwent follow-up over 6 months. The significance of clinical characteristics linked to the clinical cure rate of AUB was examined by logistic regression. Results: There were 64 clinically cured (43.5%) and 83 non-clinically cured (56.5%) patients in the study. There were no significant differences in the age, menstrual duration, gravidity, parity, number of cesarean sections, time since the previous cesarean section, uterus position, width, depth, and thickness of the remaining muscle layer of the defect by MRI T2-weighted images (T2WI) before hysteroscopic surgery between the 2 groups. MRI T2WI of the myometrial thickness adjacent to the defect [P=0.038, odds ratio (OR) =2.095, 95% confidence interval (CI): 1.047-4.261] and the distance from the defect to the external cervical os (P=0.021, OR =2.254, 95% CI: 1.136-4.540) before hysteroscopic surgery are risk factors for the clinical cure rate. Conclusions: The myometrial thickness adjacent to the defect and the distance from the defect to the external cervical os in preoperative MRI are risk factors for clinical cure rate in patients with PCSD-related AUB after hysteroscopic treatment, which is helpful for evaluating the prognosis of disease.
