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
backgroundRectal purse string placement for transanal mesorectal excision is challenging, and practice is difficult. The objective of this study is to build an endoscopic rectal purse string simulator and provide evidence for the validity of its use.
methodsA low-cost transanal endoscopic rectal purse string simulator was created and used to measure the performance of participants. Participants included general surgery residents, fellows, and staff surgeons from several Canadian university-affiliated institutions across Canada. The performance of the rectal purse string placement was measured by the time to completion of the task as well scoring with a modified objective structured assessment of technical skills (OSATS) score and a modified advanced laparoscopic suturing (ALS) score.
resultsThirty-nine participants were recruited into the study. Participants were split into three groups, based on prior experience with laparoscopic suturing, for the analysis of suturing a rectal purse string on the simulator based on three performance measures. There was a significant difference found in all three measures of performance in the three groups (time to completion p = 0.014, mean blinded OSATS score p = 0.007, mean blinded ALS score p = 0.020). Participants with previous laparoscopic suturing had significantly faster times to completion and higher skills scores when compared to residents (time: 5.1 ± 1.4 min vs 9.0 ± 4.8 min, p = 0.005; OSATS: 19.7 ± 2.8 vs 13.0 ± 5.8, p = 0.00398, ALS: 27.4 ± 4.0 vs 18.9 ± 8.5, p = 0.0151).
conclusionsA transanal endoscopic purse string simulator was constructed and preliminary testing has shown variable performance based on prior laparoscopic suturing experience.
