- Numbers of positive anti-HEV IgG serum samples/total samples in patients with different age groups were demonstrated in percentages per year (2015–2018). Chi-square test was used to analyze the association between age group and anti-HEV IgG seropositivity. A P-value less than 0.05 is considered statistical significance
