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

introductionIn this study, we aimed to assess the effect of SARS-CoV-2 infection on semen parameters in one group of patients before and after infection.

methodsPatients were screened if they had a semen analysis performed between October 1, 2019, and December 1, 2020, in the assisted reproduction unit and later had positive polymerase chain reaction (PCR) test for SARS-CoV-2 infection. The patients' semen parameters were recorded before and after SARS-CoV-2 infection, along with degrees of SARS-CoV-2 infection, dates of SARS-CoV-2 infection, durations between the treatment for SARS-CoV-2 infection and the second semen analysis, time of symptom onset, duration of their symptoms, ages, comorbidities, and any medications patients were taking.

resultsForty-one patients were included in the study. The mean age of the patients was 31.29±5.95 years. The mean duration from first semen analysis to the PCR test was 7.74±3.03 months. The mean duration between the PCR test and later semen analysis was 2.35±1.35 months. The median sperm concentration for the patients before and after SARS-CoV-2 infection were 24 mil/ml and 13 mil/ml, respectively (p<0.001). The normal morphology percentage before infection was 3.16±0.92, while it was 2.44±1.04 after infection (p=0.011). In 26 patients, the period from the time of infection to the second semen analysis was over 70 days, while this period was less than 70 days in the other 15 patients. In both patient groups, a significant decrease was detected in the sperm concentrations and total sperm count.

conclusionsIn the semen samples we assessed, we observed a significant decrease in the mean sperm concentration, total sperm count, and mean percentage of samples with normal morphology after SARS-CoV-2 infection.
