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

Chronic hepatitis B virus (HBV) infection is a global public health problem, and many regions of Sub-Saharan Africa are disproportionately affected, including Cameroon, where prevalence has previously been shown to be high. This study aimed to provide up-to-date estimates of HBV prevalence in Cameroon. We searched Medline, Global Health, Embase, Web of Science, Cochrane Library, Africa Index Medicus and the Journal of Health Science and Disease at the University of Yaounde. We included studies reporting HBV surface antigen (HBsAg) prevalence in the general population and subpopulations. A random-effects meta-analysis was used to generate pooled estimates of HBsAg prevalence, overall and for population subgroups including those considered at relatively higher-risk and relatively lower-risk of HBV infection. Heterogeneity was assessed using the index of heterogeneity (I
