EFFICACY OF LOW-LEVEL LASER THERAPY ON FISTULA-IN-ANO TREATMENT.
Article in Arquivos brasileiros de cirurgia digestiva : ABCD = Brazilian archives of digestive surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundFistulous area being A control and B laser group: Arrows indicate fistulous tract much thinner in B. Treating anal fistulae is still a great challenge due to the possibility of fecal incontinence after surgery and that the use of laser has been gaining space in medicine, including as an inducing method of healing.
aimTo evaluate the efficacy of low-level laser therapy on fistula-in-ano treatment in rats.
methodsFifteen male Wistar rats weighing approximately 250-300g were used, which were subjected to the anal fistula induction procedure and after 30 days were distributed into two groups: control group (CG, n=5) and laser group (LG, n=10) observed for another 30 days. In the CG no treatment was performed and, in the LG, low-level laser therapy was applied in fistulous tracts daily. The closure of the fistulous tract, the area of the remaining tract, the inflammatory infiltrate and vascular congestion were evaluated.
resultsThere was no complete closure of the tract in any of the animals. The mean area of the remaining tract was 847.2 µm2 in the CG and 248.5 µm2 in the LG (p=0.001). The mean inflammatory infiltrate score was 2.4 in the CG and 1.3 in the LG (p=0.0285), while in the evaluation of vascular congestion, 1.6 was observed in the CG and 0.6 in the LG (p=0.031).
conclusionsLow-level laser therapy was able to reduce the area of the fistulous tracts as well as decrease the inflammatory process and local vascular congestion.
