Prevalence and molecular characterization of occult hepatitis B virus in pregnant women from Gondar, Ethiopia.
Article in Canadian liver journal, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 1 of them a synthesis that pooled 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.
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
Background: The greatest risk of chronic hepatitis B (CHB) is from mother-to-child transmission. Approximately 20% of individuals in sub-Saharan Africa are hepatitis B virus (HBV) surface antigen-positive (HBsAg+), but the prevalence of occult hepatitis B (OHB) is unknown. Aim: This study investigated CHB and OHB prevalence and viral variants in a cohort of pregnant women in Gondor, Ethiopia. Methods: Patients were prospectively recruited from the University of Gondar Hospital ( Results: Of women tested, 1% (2/200) were HBsAg+; 26.8% (47/182) of HBsAg-negative patients were anti-HBc+, of whom 37/47 (78.7%) had detectable HBV DNA. The overall rate of OHB was 20.3%. Both HBsAg+ cases were HBV genotype D, and 36/37 (97.3%) of OHB individuals were genotype D. None carried VEM, but both HBsAg+ cases and 32/37 (86.5%) of the OHB cases showed lamivudine-resistant mutations. Conclusions: Twenty-seven percent of pregnant women in this cohort showed evidence of CHB or prior HBV exposure (ie, HBsAg+ or anti-HBc+) and clinically relevant HBV variants. Data from this single-centre study suggests high HBV prevalence, reinforcing the World Health Organization's recommendation for universal prenatal HBV screening and infant vaccination.
