Factors affecting patency time and semen quality in a single-armed microsurgical vasoepididymostomy.
Article in Asian journal of andrology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
abstractAlthough microsurgical vasoepididymostomy (MVE) is an effective treatment for epididymal obstructive azoospermia, some patients may experience delayed patency or suboptimal semen parameters after patency. However, research into patency time, semen quality postpatency, and associated influencing factors remains limited. This study aimed to address these issues by evaluating 181 patients who underwent at least one-sided MVE employing asingle-armed longitudinal intussusception vasoepididymostomy technique, with a follow-up period of over 12 months for 150 patients. The overall patency rate was 75.3%, with 86.0% of patients achieving patency within 6 months following MVE. Unexpectedly, factors such as age, history of epididymitis, duration of surgery, side of anastomosis, sperm motility in epididymal fluid, and the site of anastomosis showed no correlation with patency time. Nonetheless, our univariate and multivariate linear regression analysis indicated that only the site of anastomosis was positively correlated with and could independently predict postoperative total motile sperm count. Therefore, the site of anastomosis might serve as a predictor for optimal postoperative semen quality following the MVE procedure.
