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 Fistula in ano is a persistent anorectal condition associated with pain, discharge, and recurrence. Traditional procedures such as fistulotomy and fistulectomy remain the standard of care for simple fistulae but may be associated with postoperative discomfort, delayed healing, and potential sphincter injury. Medicated seton offers a sphincter-preserving alternative that may enhance healing and reduce morbidity. The present study aims to compare the clinical effectiveness and safety of medicated seton versus fistulotomy or fistulectomy in the treatment of simple anal fistula. Methods This prospective comparative study enrolled 50 patients with simple anal fistula (St. James Grade I-II) between January 2024 and June 2025. In accordance with American Society of Colon and Rectal Surgeons (ASCRS) guidelines, only simple low intersphincteric and low trans-sphincteric fistulas were included. Patients were allocated into two groups of 25 each: medicated seton or fistulotomy/fistulectomy. Parameters assessed included operative time, postoperative pain (visual analog scale (VAS) at six hours), hospital stay, complications, work-off period, healing time, recurrence, patient satisfaction, and overall efficacy. Data were analyzed using the t-test and chi-square test, with p < 0.05 considered significant. Results Baseline demographics were comparable between groups. Operative time was significantly lower in the medicated seton group (18.6 ± 3.2 minutes) compared with the fistulotomy/fistulectomy group (28.4 ± 4.5 minutes; p < 0.001). Hospital stay (2.3 ± 0.8 vs 4.1 ± 1.2 days; p < 0.001) and postoperative pain scores (3.1 ± 1.2 vs 6.4 ± 1.6; p < 0.001) were also significantly reduced with medicated seton. Postoperative complications were low in both groups, with wound infection occurring in 2 (8%) vs 6 (24%), bleeding in 1 (4%) vs 3 (12%), and flatus incontinence in 0 vs 2 (8%) patients, respectively. Recovery outcomes favored medicated seton, including a shorter work-off period (8.2 ± 2.4 vs 15.6 ± 3.7 days; p < 0.001) and faster healing (6.2 ± 1.5 vs 8.9 ± 1.8 weeks; p < 0.001). Recurrence at three months was low in both groups, occurring in 1 (4%) vs 3 (12%) patients (p < 0.602). Overall efficacy was achieved in 23 (92%) patients in the medicated seton group compared with 19 (78%) in the fistulotomy/fistulectomy group. Conclusion Medicated seton was associated with reduced operative time, decreased postoperative pain, shorter hospitalization, quicker return to routine activities, and favorable healing outcomes. It offers a safe, effective, and sphincter-preserving option for managing simple anal fistula, with comparable recurrence rates to traditional surgery.
