SY, Soyangin constitution; TE, Taeumin constitution; SE, Soeumin constitution; M, male; F, female; na, not available. 1Multivariated adjusted odds ratio HRV analysis. The odds ratio adjusted for age, gender, education period, marital status, drinking status, smoking status, past history (hypertension, diabetes mellitus, and hyperlipidemia), BMI, and metabolic syndrome. 2HRV reporting generated indices (stress index, fatigue index) and TP showed a significant difference between constitution groups.
