Seroprevalence of Hepatitis-E infection in healthy blood donors in an endemic country.
Article in Pakistan journal of medical sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: To determine the frequency of Hepatitis-E prevalence among blood donors at a tertiary care hospital in Karachi. Methodology: A cross-sectional study was conducted among healthy blood donors at the blood donation facility of Liaquat National Hospital (LNH) by Departments of Gastroenterology, Hepatology and Microbiology from October 2020 to January 2022. The blood samples were screened for Hepatitis E virus (HEV) using anti-HEV antibodies (IgG and IgM). Those who tested positive for anti-HEV IgM were tested for HEV-RNA by real-time reverse transcription polymerase chain (PCR). Results: A total of 515 individuals were screened. The mean age was 30.08±7.56 years, and all were males. The mean ALT values recorded were 42.8447±32. Anti HEV IgG was positive in 366 individuals (71%). Anti HEV IgM was positive in 31 (6%) individuals, but HEV - RNA PCR was negative in all IgM+ individuals. Conclusion: The high seroprevalence of Anti HEV IgM among healthy blood donors emphasizes the need for robust measures of routine screening for HEV of all blood products in endemic countries to prevent transfusion dependent transmission with special consideration when the recipients are either immunocompromised or pregnant.
