Abbreviations: IgG CMV− cytomegalovirus seronegativity, IgG CMV+ cytomegalovirus seropositivity. The comparison between active and inactive group concerns CMV seropositive participants. The measurements in groups are compared by the one-way ANOVA or the Mann-Whitney non-parametric test (if the normality assumption is violated)
