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

backgroundCoronavirus disease 2019 (COVID-19) has spread rapidly worldwide since its discovery in December 2019. Research published since the COVID-19 outbreak has focused on whether semen quality and reproductive hormone levels are affected by COVID-19. However, there is limited evidence on semen quality of uninfected men. This study aimed to compare semen parameters among uninfected Chinese sperm donors before and after the COVID-19 pandemic to determine the impact of the COVID-19 pandemic-related stress and lifestyle changes on uninfected men.

resultsAll semen parameters were non-significant except semen volume. The average age of sperm donors was higher after the COVID-19 (all P < 0.05). The average age of qualified sperm donors increased from 25.9 (SD: 5.3) to 27.6 (SD: 6.0) years. Before the COVID-19, 45.0% qualified sperm donors were students, but after the COVID-19, 52.9% were physical laborers (P < 0.05). The proportion of qualified sperm donors with a college education dropped from 80.8 to 64.4% after the COVID-19 (P < 0.05).

conclusionAlthough the sociodemographic characteristics of sperm donors changed after the COVID-19 pandemic, no decline in semen quality was found. There is no concern about the quality of cryopreserved semen in human sperm banks after the COVID-19 pandemic.
