Characteristics and post-operative outcomes of surgery for fistula-in-ano managed at a tertiary care hospital in Sri Lanka: a retrospective 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
objectivesManagement of fistula-in-ano is associated with recurrence and, occasionally, with anal incontinence. We investigated the clinical characteristics and outcomes of fistula-in-ano.
methodsWe included patients with fistula-in-ano managed at a tertiary care center (2016-2021). We collected clinical characteristics and 1-year outcomes using questionnaires. The chi-square test was used in statistical analysis.
resultsIn total, 284 patients (231 men, 81.3%; median age 39.5 [range: 7-73] years) were included. Most patients had simple fistulae (n = 191, 67.3%). Transphincteric (n = 110, 38.7%) fistulae were the most common type, followed by intersphinteric fistulae (n = 103, 36.6%). Fistulotomy (n = 157, 55.3%) was the most common procedure. Follow-up details were traceable in 157 (55.3%) patients. At 1 year, the overall healing rate was 88.5% (n = 136). There was no association between type of surgical procedure and incontinence. The mean Vaizey score, used to assess anal incontinence, was 0.84 (range: 0-14). Incontinence was observed in 32 patients (20.9%), and flatus incontinence was the most common type (n = 17, 53.1%). Complex fistulae were associated with higher recurrence rates than simple fistulae (32.6% vs. 2.8%).
conclusionThe healing rate in surgical treatment of fistula-in-ano was 88.5%, with acceptable complication rates. There was no association between surgical procedure type and incontinence.
