Varicella-Zoster Virus Infection in Pregnancy: Maternal, Fetal, and Neonatal Implications in the Vaccination Era.
Review in Microorganisms, 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
Infection by the varicella-zoster virus (VZV) during pregnancy is uncommon but clinically relevant, since it may compromise both the mother and the fetus. Although varicella is generally benign and self-limited in childhood, the physiological and immunological changes in pregnancy predispose individuals to more severe forms of the disease, with pneumonia representing the main maternal complication and a leading cause of morbidity and mortality. Vertical transmission may result in congenital varicella syndrome, the most severe fetal consequence, whose risk is greatest between the 13th and 20th weeks of gestation, or in severe neonatal varicella when maternal infection occurs in the peripartum period. This article presents a narrative review of the literature. To enhance methodological transparency and reproducibility, key principles of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were applied to the literature search and study selection process. Searches were conducted in the PubMed/MEDLINE and SciELO databases, and 32 studies were included in the narrative synthesis. The review addresses the virology, pathophysiology, and epidemiology of VZV infection, including differences between temperate and tropical regions, as well as its clinical manifestations and maternal, fetal, and neonatal complications. Diagnosis is predominantly clinical, with the polymerase chain reaction being the most sensitive and specific confirmatory method and serology being useful mainly for the assessment of maternal immunity. Management encompasses the assessment of susceptibility, post-exposure prophylaxis according to current guideline recommendations, and early antiviral treatment of established infection. Preconception and postpartum vaccination remain the main preventive strategies. Despite recent advances, important gaps persist regarding prophylactic strategies and the long-term safety of antivirals during pregnancy.
