% CD3⁺E tetramer positive means percent of CD3⁺ cells that are E tetramer positive

% CD56⁺CD3^-E tetramer positive means percent of CD56⁺CD3^- cells that are E tetramer positive

Values represent the mean ± SD. One-factor ANOVA was done when variance of each group was equal by Bartlett test. For multiple comparisons, we used Sheffé F to analyze statistical difference

AC indicates asymptomatic carrier

If variance of each group was different, Kruskal-Wallis test was used
