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

backgroundVasoepididymostomy (VE) is an important surgical treatment to achieve natural conception for patients with obstructive azoospermia (OA), and only unilateral VE can be performed under certain conditions, such as OA patients with congenital unilateral absence of the vas deferens (CUAVD) and some acquired OA. There is a lack of relevant reports assessing the clinical outcomes of unilateral VE in OA patients with different causes. This study is aimed to describe the clinical features and evaluate treatments and outcomes of unilateral single-armed VE in OA patients.

methodsFrom December 2015 to June 2021, 46 OA patients (including 13 CUAVD-associated OA and 33 acquired OA) underwent unilateral single-armed VE in Shanghai General Hospital (Shanghai, China). Patient information, semen analysis, hormone profiles, and treatment information were collected, and the clinical outcomes were evaluated.

resultsObstruction in distal of unilateral vas deferens (16/46) was the most common cause for OA patients underwent unilateral VE, and CUAVD accounts for 28.4% (13/46). The overall patency rate was 50.0% (23/46), with 38.5% (5/13) for the CUAVD group and 54.5% (18/33) for the acquired group (p > 0.05). The natural pregnancy rates in CUAVD group and acquired group were 20.0% and 33.3%, respectively (p > 0.05).

conclusionsThese findings suggest unilateral single-armed VE can achieve high patency and pregnancy rates in OA patients, whether for CUAVD or acquired OA patients.
