Note:

^†Nonparametric correlation was performed using ordered numbers for sex (female = 0, male = 1), balanced constitution (balanced constitution = 1, unbalanced constitution = 0), and yang-deficiency constitution (yang-deficiency = 1, no yang-deficiency = 0). Statistical significance of the correlation is indicated by:

^*P < .05,

^**P < .01, and

^***P ≤ .002. N = 227, 59, 49, and 65 for Oxygen consumption rates (OCRs), citrate synthase, malondialdehyde, and Adenosine triphosphate (ATP), respectively.
