1 · What the graph read from it

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.

2 · The registry

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

objectivesWe reviewed surgical outcomes after introducing a novel surgical technique for anal fistula surgery designed to preserve anal sphincter function and the anoderm.

methodsWe studied 200 male patients who underwent a functional preservative operative technique (FPOT group) for anal fistulas and 200 patients who underwent resection of trans-sphincteric anal fistulas (fistulectomy group) between February 2014 and September 2015. We compared complications, such as those affecting anal sphincter function, recurrence, and incontinence.

resultsFistulas recurred in three (1.5%) patients in the FPOT group and two (1%) patients in the fistulectomy group. This difference was not significant. Other complications included gas leakage and other forms of incontinence in 1 (0.5%) and 14 (7%) patients in the FPOT and fistulectomy groups, respectively. Anal function assessment demonstrated that the FPOT was significantly better at preserving function than fistulectomy in all patients.

conclusionsThere were no significant differences between the FPOT and fistulectomy in terms of recurrence or complication rates. Also, because there was no decrease in postoperative anal function, we concluded that the FPOT is an effective preservative surgical technique for treating trans-sphincteric anal fistulas.
