Associations between adiposity measures and 24-hour urinary norepinephrine and epinephrine excretion rates during isocaloric conditions. Association between urinary norepinephrine excretion and (A), body mass index (BMI) and (B), percentage body fat by dual-energy X-ray absorptiometry (DXA). Association between urinary epinephrine excretion and (C), BMI and (D), percentage body fat by DXA. Black circles denote male, white circles denote female participants. Y-axes are formatted on a logarithmic scale (log₁₀) to account for the skewed data distribution of raw catecholamine values.
