Data from a systematic literature review to determine the relationship between HBsAg (prevalence of HBV infection) and anti-HBc (exposure to HBV infection) in African populations.
Meta-data table: Data extracted from studies identified in a systematic literature search for studies including anti-HBc and HBsAg prevalence data for African countries published between 1995-2019. A total of 96 studies spanning 39 African countries were identified in the search, generating 109 unique data points representing independent cohorts. A PMID or DOI is provided for each manuscript. When a PMID or DOI could not be found (n=2), ISI or ISSN was provided. A key and notes on the table is given at the foot of the table.
Quality assessment table: formal assessment of the 96 studies included in the meta-analysis. Studies were assessed using established guidelines from the Johanna Briggs Institute for the critical appraisal of the scientific literature (1). Complete metadata for the manuscript are available in Table 1. All studies included in this analysis assessed the prevalence of HBsAg and anti-HBc. The sample size required for each was different. Sample size was assessed using guidelines established by Naing et al, (2006) (2). Notes on the studies are given at the foot of the table.
