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 evaluate the outcome and safety of transanal drainage tube (TDT) placement following surgical repair of chronic third- and fourth-degree perineal tears. Patients and Methods: A retrospective cohort study was conducted at Peking Union Medical College Hospital (2016-2024), including 31 patients with chronic perineal tears who underwent surgical repair. Patients were stratified into success (n=23) and failure (n=8) groups. Surgical failure was defined as persistence of fecal incontinence at six months postoperatively. Data included demographics, surgical details, TDT use, Wexner, and SF-12 scores. Results: The procedure demonstrated an overall success rate of 74.2% (23/31). Postoperative SF-12 and Wexner scores improved significantly in both the success and failure groups (p < 0.05). The success group had longer tube retention (9[7-11.5] vs 7[6-7] days, p=0.03). Further analysis revealed that prolonged drainage duration beyond 8 days was associated with improved success rates. Patients in the TDT group showed significantly greater improvement in Wexner scores (11.42 ± 3.13 vs 7.67 ± 3.37, p = 0.004). No major TDT-related complications occurred. Conclusion: Transanal drainage tube placement may enhance anal sphincter function when used at the time of anal sphincteroplasty. Maintaining TDT for more than 8 days is associated with higher success rate. Both successful and unsuccessful repairs lead to significant improvements in quality of life and fecal incontinence symptoms.
