r, partial correlation after controlling for age, gender, ethnicity; *, partial correlation after controlling for age, gender, ethnicity, and ln(BMI); BMI, body mass index; WHR, waist-to-hip ratio; PFAT, percent of fat mass (measured by DXA). N =  sample number, p =  p-value; SVF, stromal vascular fraction.
