Low prevalence of concurrent active hepatitis E and B virus infection in high-risk groups in Southwestern Cameroon.
Article in IJID regions, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Objectives: Coinfection with the hepatitis E virus (HEV) and hepatitis B virus (HBV) can have clinical implications, particularly in immunocompromised and high-risk populations. This study investigated HEV seroprevalence and viraemia among individuals with HBV exposure in the Southwest region of Cameroon. Methods: We analyzed three cohorts with prior HBV exposure, defined as anti-HBc total positivity: HIV-infected individuals (n = 174), pregnant women (n = 87), and blood donors (n = 167). Participants were screened for anti-HEV immunoglobulin (Ig)G and IgM using an enzyme-linked immunosorbent assay, and HEV RNA was detected by reverse transcription-polymerase chain reaction. HBV DNA was quantified in those with hepatitis B surface antigen positivity. Results: Among anti-hepatitis B core total-positive participants, anti-HEV IgG seroprevalence was 8.6% in HIV-infected individuals, 5.7% in pregnant women, and 12.0% in blood donors. Anti-HEV IgM was detected in 1.7%, 0%, and 1.2%, respectively. Also, HEV RNA was detected in two blood donors (genotype 3a) and two pregnant women (genotype 3e), but not in HIV-infected individuals. No cases of concurrent active HBV and HEV replication were observed. Conclusions: Previous HEV exposure is relatively common in this region, but active HBV-HEV coinfection appears rare among HIV-infected individuals, pregnant women, and blood donors in Southwest Cameroon.
