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

This study is to evaluate the effectiveness of a modified single-armed suture technique for microsurgical vasoepididymostomy (VE) in patients with epididymal obstructive azoospermia. From September 2011 to December 2011, microsurgical two-suture longitudinal intussusception VEs were performed using our modified single-armed suture technique in 17 men with epididymal obstructive azoospermia at our hospital. Two of these patients underwent repeated VEs after previous failed VEs, and one patient underwent unilateral VE because of an occlusion of the left abdominal vas deferens. The presence of sperm in the semen sample at 3 months postoperation was used as the preliminary endpoint of this study. Each patient provided at least one semen sample at the 3-month time point, and the patency was assessed by the reappearance of sperm (>10(4) ml(-1)) in the semen. The mean operative time for the modified technique was 219 min. Patency was noted in 10 men (58.8%), including one patient who underwent repeated VE. The patient who underwent unilateral anastomosis manifested no sperm postoperatively in his semen. Sperm granulomas were not detected in this cohort. The results of this study demonstrate that our modified technique for microsurgical longitudinal intussusception VE is effective. We believe that it is a practical alternative that may reduce operation time and obviate the suture crossing.
