  • a Values are medians (25th to 75th quartiles). There were no significant differences in RV-specific IgA titers among the three groups. Significant differences in RV-specific IgG titers in plasma among the three groups were as follows. For the control versus the AD and PD groups, P = 0.002. For the control versus the AD group, P < 0.001. For the control versus the PD group, P = 0.024. The Kruskal-Wallis test was used for comparisons among all three groups; the Mann-Whitney U test was used for comparisons between two groups.
