1 · What the graph read from 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.

2 · The registry

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

backgroundHepatitis B virus (HBV) infection remains a critical global health issue, affecting over 254 million individuals and causing approximately 1.2 million new infections annually. This systematic review and meta-analysis is aimed at estimating the pooled prevalence of HBV infection and identifying associated risk factors among pregnant women in West African countries.

methodsWe conducted a systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched Ovid Medline, Ovid Global Health, Ovid Embase, Web of Science, African Journals Online (AJOL), and African Index Medicus for studies on HBV infection in pregnant women in West African countries. We assessed the methodological quality of the included studies using the Hoy et al. tool. The random-effects model was used to calculate the pooled prevalence of HBV infection, whereas the I

resultsThis analysis included 138 studies from 11 West African countries. The pooled prevalence of HBV infection, based on HBsAg seropositivity, was 8.0% (95% CI: 7.3-8.6), with significant heterogeneity between studies (I

conclusionThis systematic review reveals a substantial prevalence of HBV infection among pregnant women in West Africa, underscoring the urgent need to enhance prevention efforts. Improved access to diagnostic testing and vaccination remains essential to achieving HBV elimination in this population.
