Results of lymphocyte proliferation assays in response to recombinant HEV ORF2 protein among patients with acute hepatitis E (solid bars) and healthy controls (empty bars). The bars indicate stimulation indices in the presence of recombinant hepatitis E virus ORF2 protein (10 μg/mL). The horizontal line indicates the cut-off (2.0), above which stimulation indices were considered as significant. Stimulation indices in patients were higher than those among controls (medians 2.6 and 1.3, respectively; P = 0.002, Wilcoxon’s rank sum test). The numbers on X-axis represent serial numbers for patients and controls. Hatched lines represent the two patients (19 and 25) who had fulminant hepatic failure.
