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
Urethral injury is one of the crucial intraoperative complications during transanal total mesorectal excision (taTME) for male patients with low rectal cancer. Urethral injury can occur during the anterior dissection around the inferior lobe of the prostate and the membranous urethra. A tool to visualize the urethra around this area would be useful to avoid urethral injury. We report a cadaveric demonstration of visualization of the urethra using a lighted stent during transanal intersphincteric resection. The lighted stent (InfraVision Ureteral Kit, Stryker) was placed through the irrigation channel of a clear three-way urinary catheter. After the anterior dissection, the visibility of the lighted stent was investigated under the three laparoscopic light conditions: (1) normal intensity; (2) low intensity; and (3) turned-off. In the proper dissection plane that led to preservation of the urethra, the lighted stent was hardly visible under the normal-intensity condition, but it was clearly visible under the turned-off condition. In the improper dissection plane that led to urethral injury, the lighted stent was clearly visible under both the normal-intensity and the turned-off conditions. Visualization of the urethra using the lighted stent under the turned-off condition of the laparoscopic light can be useful to avoid inadvertent urethral injury during the anterior dissection of male taTME. Clear visibility of the lighted stent under the normal-intensity condition can indicate that the dissection plane is too close to the urethra.
