Abbreviations: NPC, nasopharyngeal carcinoma; VCA-IgA, viral capsid antigen-immunoglobulin A; EBNA1/IgA, Epstein–Barr nuclear antigen 1-immunoglobulin A; BMI, body mass index; IQR, interquartile range. Data are presented as median (interquartile range) for adiponectin. a p-values were calculated by Mann–Whitney U test.
