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

purposeDuring laparoscopic inguinal hernia repair, the inferior epigastric vessels (IEVs), vas deferens, and spermatic vessels are often used as landmarks for horizon adjustment during camera navigation. The present study investigated the visual angle of landmarks around the internal inguinal ring using recorded video clips.

methodsThe angle of the IEVs, vas deferens, spermatic vessels, and the degree of lateral tilt of the scope were measured using a video clip. The angle of the median line of the vas deferens and spermatic vessels (MVS) was also calculated.

resultsBetween 2018 and 2022, 70 inguinal hernia lesions underwent robot-assisted inguinal hernia repair. Under adjustment according to lateral tilt of the scope, the mean angles of the IEVs and MVS were 14.1° laterally (SD = 15.9°) and -1.5° medially (SD = 15.8°), respectively.

conclusionThe IEVs and MVS do not always adopt an absolutely vertical course, and some structures run obliquely. The angles of the IEVs and MVS should, therefore, be confirmed at the beginning of the operation to guide horizon adjustment.
