The Effect of Hepatitis B Virus Infection on Semen Quality of Infertile Men: A Systematic Review and Meta-Analysis of Observational Studies.
Article in International journal of fertility & sterility, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Semen quality is considered as an alternative measure for men's fertility. Several studies have examined the association between the hepatitis B virus (HBV) infection and semen quality, but the findings have been inconclusive. This study investigated the effects of HBV on semen quality. This systematic review and meta-analysis was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) 2020, as well as Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guideline. In this study, international electronic databases including PubMed (National Library of Medicine), Web of Science, Scopus and Cochrane Library and also Persian databases including Scientific Information Database (SID) and Magiran were searched without a time limit until June 2023. All cohort and case-control studies examining the effects of HBV infection on the semen parameters of infertile men were included in the study. Animal studies, letters to the editor and case reports were excluded. The Newcastle-Ottawa scale was used to evaluate the quality of the included articles. Data analysis was done with Stata software. Of the 913 studies, 13 observational studies comprised a total of 10156 patients were included in this review, nine of which were included in the meta-analysis. The results showed that HBV infection has a negative effect on semen volume (95% confidence interval (CI): [-0.33, -0.09], P<0.001), sperm concentration (95% CI: [-8.53, -2.66], Pv<0.001), sperm motility (95% CI: [-10.06, -3.39], P<0.001), sperm normal morphology (95% CI: [-6.42, -1.06], P<0.001) and sperm viability (95% CI: [-11.64, -0.31], P<0.001). These results suggest that the HBV infection has a negative effect on the semen quality in infertile men. Nonetheless, further research with more robust design is recommended.
