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
backgroundThe aim of the present study was to evaluate the surgical technique, short-term oncological and perioperative outcomes for the transabdominal division of the levator ani muscles during abdominoperineal excision of the rectum (APER).
methodsA systematic review was performed to identify studies reporting on transabdominal division of the levator ani during APER. A comprehensive literature search was performed using a combination of free-text terms and controlled vocabulary when applicable on the following databases: MEDLINE, EMBASE, Science Citation Index Expanded and Cochrane Central Register of Controlled Trials in the Cochrane Library. The search period was from January 1945 to December 2015. The following search headings were used: "transabdominal", "transpelvic", "abdominal" or "pelvic" combined with either "levator" or "extralevator" and with "abdominoperineal".
resultsNine publications were identified reporting on 99 participants. The male/female distribution was 1.44:1, respectively, and the mean age was 56.6 (30-77) years. All tumours were less than 5 cm from the anal verge. The preoperative radiological staging was T2 in 18% of cases, T3 in 53.5% and T4 in 28.5%. Transabdominal division of the levators was performed laparoscopically in 55 cases, robotically in 34 and open in 10. The mean operating time was 255 (177-640) min. Mean intraoperative blood loss was 140 (92-500) ml. There were no conversions to open. Circumferential resection margins were positive in two cases, and there was one intraoperative perforation. Mean post-operative length of stay was 9.3 (3-67) days. Follow-up (from 0 to 31 months) revealed 19 perineal wound infections, 15 cases of sexual dysfunction and 7 cases of urinary retention. There was no mortality and 1 readmission.
conclusionsTransabdominal division of the levators during APER is feasible and reproducible, with acceptable perioperative and good early oncological outcomes. Further comparative studies are needed.
