Hepatitis B virus impacts embryonic development and methylation of maternal genes in assisted reproductive technology patients.
Article in Journal of assisted reproduction and genetics, 2025. 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
purposeIn China, the prevalence of hepatitis B virus (HBV) infection among infertile couples is a significant clinical problem. It is necessary to determine the effect of HBV infection on embryo development.
methodsThe 4301 fresh cycles and 5763 frozen embryo transfer (FET) cycles were grouped according to the couple with or without HBV infection. The embryo fertilization rate, cleavage rate, transplantable embryo rate, and rate of high-quality embryos were analysed. The methylation status of maternal antigen that embryos require (MATER), zygote arrest 1 (ZAR1) and growth differentiation factor 9 (GDF9) genes in the peripheral blood of assisted reproductive technology (ART) women was detected by methylation-specific polymerase chain reaction (MSP).
resultsThe pregnancy rate of the female HBV-positive group was significantly lower than that of the HBV-negative group. The fertilization rate of intracytoplasmic sperm injection (ICSI) cycles in the male HBV-positive group was significantly lower than that of the male HBV-negative group. There were no differences in biochemistry or clinical pregnancy rates among the FET groups. The promoter methylation of GDF9 in HBV-positive ART women was higher than that in HBV-negative ART women, and that of ZAR1 in HBV-positive ART women was lower than that in HBV-negative ART women.
conclusionIt was a detrimental effect of HBV infection on in vitro fertilization (IVF) and ICSI treatment outcomes in women. The HBV infection was associated with the maternal genes promoting methylation.
