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
aimAlthough various sphincter-preserving techniques exist for treating anal fistulas, none have demonstrated clear superiority. Therefore, the aim of this study was to introduce a novel sphincter-preserving technique for anal duct ligation and muscle closure (ALMC) and analyse its perioperative outcomes.
methodThe data for patients who underwent ALMC for fistula-in-ano at Seoul Song Do Hospital between 2009 and 2023 were retrospectively reviewed. Patient demographics, intraoperative information and postoperative outcomes were assessed. The main outcomes were recurrence and wound healing. Recurrence was defined as the presence of a fistula tract or discharge more than 12 weeks after the primary surgery after achieving complete healing. Faecal incontinence was also investigated clinically.
resultsOverall, 556 patients (84.0% male; mean age 41.7 ± 12.3 years) underwent ALMC. Among these, 152 (27.3%) had a history of fistula surgery and 261 (46.9%) had suprasphincteric fistulas. Fistula-in-ano recurred in 33 patients (5.9%), wound healing was delayed in 97 (17.4%) and faecal incontinence was observed in 12 (2.2%). The mean follow-up duration was 10.0 ± 16.0 months, and the average duration until recurrence was 13.8 ± 10.7 months. The proportion of suprasphincteric fistulas was similar in those who experienced recurrence and those who did not (57.6% vs. 46.3%, respectively; p = 0.239). The proportion of suprasphincteric fistulas in the delayed wound healing group was slightly higher, although the differences were not statistically significant (56.7% vs. 44.9%, respectively; p = 0.054).
conclusionALMC appeared to be a safe and feasible option for treating anal fistulas, providing good perioperative outcomes, particularly when sphincter preservation was crucial.
