Average log(MFI) anti-EBV antibody levels by age in years. Mean (•) and standard deviation (\({ \vdash }\)) median fluorescence intensities (MFI) of anti-Epstein–Barr Virus (EBV) log-transformed antibody levels by age in years for A EBV-nuclear antigen (EBNA-1), B early antigen (EAd), C viral capsid antigen (VCA), and D EBV Seropositivity by age in years. EBV seropositivity was measured as detection of anti-EBV antibodies to EBNA-1, EAd, or VCA
