The impact of maternal chronic viral hepatitis infections on pregnancy and neonatal outcomes in in vitro fertilization: a systematic review and meta-analysis.
Synthesis in Journal of ovarian research, 2026. 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
backgroundChronic hepatitis B (HBV) and hepatitis C (HCV) infections represent a substantial global health burden and increasing numbers of infertile women with chronic HBV/HCV infections seek conception through in vitro fertilization (IVF), raising clinical concerns regarding potential perinatal risks.
objectiveTo investigate the association between maternal viral hepatitis status and pregnancy and neonatal outcomes in IVF populations.
methodsEnglish-language publications in databases including PubMed, Embase, Cochrane Library, and Web of Science Core Collection up to June 23, 2025 were systematically searched. Eligible study designs included cohort and case-control studies. Studies were excluded if they were not IVF populations. Two independent investigators performed study selection, extracted data and assess quality. The statistical synthesis employed fixed or random effects models based on study homogeneity. Potential publication bias was assessed through Begg’s rank correlation test and Egger’s linear regression test and methodological quality of these studies was evaluated using the Newcastle-Ottawa Scale.
resultsA total of 14 eligible studies (with 12 in HBV and 3 in HCV) were included for analysis. There were no significant associations between maternal HBV infection and live birth (OR: 1.017, 95%CI: 0.936–1.105), or clinical pregnancy (OR: 0.974, 95%CI: 0.863-1.100). An increased risk of preterm delivery was found among HBV-infected mothers (OR: 1.159, 95%CI: 1.022–1.315), while no associations were found in other pregnancy outcomes and neonatal outcomes. Similarly, HCV infection showed no significant correlations with live birth (OR: 0.618, 95%CI: 0.177–2.161), or clinical pregnancy (OR: 0.585, 95%CI: 0.276–1.241).
conclusionsNeither maternal HBV or HCV infection status was associated with pregnancy and neonatal outcomes in IVF populations, except increased preterm delivery in women with HBV infection.
