Hepatitis E Virus in Individuals Undergoing Heparin Therapy: An Observational Serological and Molecular Study.
Observational study in Current drug safety, 2024. 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
introductionHeparin is derived from swine and has been suggested as a possible source of HEV. To study the potential risk of HEV infection associated with heparin treatment, two groups of individuals were compared. Sera from heparinized (N=93) and non-heparinized individuals (N=111) were tested for markers of acute HEV infection and anti-HEV IgG seroprevalence.
methodsAn acute HEV case was defined by the presence of anti-HEV IgM and/or HEV RNA. From the 93 heparinized individuals, one was positive for IgM and IgG anti-HEV and two were positive for HEV RNA (for both ORF3 and ORF2), and there were a total of two (2.2%) cases of current or recent HEV infection. From the 111 non-heparinized individuals, three were positive for IgM anti-HEV, one was positive for both IgM and IgG anti-HEV, and none was positive for HEV RNA, and there were a total of three (2.7%) cases of current or recent HEV infection. The difference between HEV cases in the heparinized individuals and the non-heparinized individuals was not statistically significant (2.2% vs. 2.7%; p = 0.799).
resultsConcerning IgG anti-HEV, it was detected in 32 individuals from the heparinized group and in 18 from the non-heparinized control group. A statistically significant difference was observed in the presence of anti-HEV IgG in heparinized individuals and controls (p = 0.003).
conclusionThis study has not found any association between heparin treatment and acute HEV infection, but has shown the use of therapeutic heparin as a risk factor for IgG anti-HEV seropositivity.
