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

study questionAre the European Association of Urology (EAU) guidelines for performing semen culture accurate enough for detecting a positive semen culture in Caucasian-European infertile men? SUMMARY ANSWER: The majority (80%) of asymptomatic infertile men with a positive sperm culture may miss a proper diagnostic assessment when relying on EAU guidelines; no single parameter can assist in medical decision-making. WHAT IS KNOWN ALREADY: The EAU guidelines suggest performing semen culture in case of increased leukocytes in semen (>10 STUDY DESIGN SIZE DURATION: A cross-sectional validation study including 523 infertile men was carried out during 2010-2018. PARTICIPANTS/MATERIALS SETTING

methodsInfertile men who were asymptomatic for genital infections were enrolled at a single academic center, and a semen culture was obtained in every case. A concentration of >10 MAIN RESULTS AND THE ROLE OF CHANCE: A positive semen culture was found in 54 men (10%). The application of EAU guidelines would have missed 43 out of 54 (80%) positive semen cultures with 120/131 (92%) useless examinations. EAU guidelines specificity, sensitivity and discrimination were 74%, 20% and 47%, respectively. When trying to improve positive semen culture prediction, we were unable to find any informative baseline parameter except for serum neutrophil-to-lymphocyte ratio (odds ratio 1.70 (95% CI 1.04-2.77)), although without any improvement in terms of discrimination ( LIMITATIONS REASONS FOR CAUTION: The study was limited by the lack of a control group of fertile men its retrospective nature. Moreover, monoclonal antibodies were not used for leukocyte assessment. WIDER IMPLICATIONS OF THE

findingsSince it is not possible to identify infertile men at risk of semen infection, further studies are needed to tailor the execution of semen culture. STUDY FUNDING/COMPETING INTERESTS: No funding was received for this study. There are no competing interests.
