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 construct a predictive model for postoperative bladder paralysis in patients with cervical cancer (CC) based on Logistic regression and nomogram. Methods: The clinical data of 220 patients with CC admitted to our hospital from December 2019 to September 2022 were retrospectively collected as the modeling cohort. In addition, the clinical data of 130 patients with CC admitted to the same hospital during a later time period, from October 2022 to September 2025, were collected as the temporal validation cohort. According to whether the patients in the modeling and validation cohorts developed bladder paralysis after surgery, they were separated into the bladder paralysis groups and the non-bladder paralysis groups. Results: Logistic regression analysis of the variables selected by LASSO regression showed that clinical staging, number of lymph nodes removed, extent of hysterectomy, width of parametrial tissue resection, and vaginal stump length were risk factors for postoperative bladder paralysis in patients with CC (P < 0.05). The AUC in the modeling cohort was 0.899, and 0.899, and the H-L test yielded χ Conclusion: Clinical staging, number of lymph nodes removed, extent of hysterectomy, width of parametrial tissue resection, and vaginal stump length were risk factors for postoperative bladder paralysis in patients with CC. The nomogram model constructed based on Logistic regression has good consistency and discrimination.
