Values are Pearson’s correlation coefficients.
* 𝑃 value < 0.05; **𝑃 value < 0.001.
¹IA-AT: internal-abdominal adipose tissue volume by MRI.
²SCA-AT: subcutaneous-abdominal adipose tissue volume by MRI.
³Total SC-AT: total body subcutaneous adipose tissue volume by MRI.
⁴US: Ultrasound.
⁵SC-abdo depth: subcutaneous-abdominal adipose tissue depth.
