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

backgroundThe endoscopic totally extraperitoneal (TEP) mesh repair is nowadays a well-established tension-free method for inguinal hernia repair. Mainly based on animal studies and case reports, a concern about the risk of postoperative infertility was expressed. This clinical study aimed to evaluate the risk of infertility due to obstructive azoospermia in men of fertile age who underwent a bilateral hernia repair.

methodsOver 3 years (2005-2008) 59 male patients, 18-60 years of age, underwent a bilateral TEP repair. Twenty-one of them were prospectively ("light mesh") and 38 retrospectively ("heavy mesh") evaluated for testicular volume and perfusion, serum levels of sexual hormones, ejaculate volume, and number of spermatic cells. Those parameters were determined preoperatively (prospective group) and not earlier than 3 months postoperatively (both groups).

resultsNo significant difference between pre- and postoperative values was detected in the prospectively studied group. All postoperative parameters were within the normal range in the retrospective group. There was no evidence of impaired fertility in any patient due to the operation.

conclusionThe standardized TEP technique for simultaneous bilateral inguinal hernia repair in male patients was not associated with a higher risk for postoperative infertility after mesh implantation. The use of heavy-weight meshes had no negative effect on fertility.
