  1. Each measure of body fluid and fat distribution was performed in separate multivariable model using linear regression, adjusted for gender, race, smoking status and SBP and unstandardized beta coefficients are reported
  2. p < 0.05 are shown in bold
  3. aOR adjusted odds ratio; CI confidence interval
