Comparison of Correlation Coefficients between BMI and BAI Using Metabolic Indices

BMI, body mass index; BAI, body adiposity index; HDL, high density lipoprotein; LDL, low density lipoprotein.

Z=(Z₁-Z₂)x√[(N-3)/(2x(1-r_x)xh)]. Z₁: Fisher Z-transformed r₁ (r₁: correlation coefficient between BMI and other variable). Z₂: Fisher Z-transformed r₂ (r₂: correlation coefficient between BAI and other variable). Z_x: Fisher Z-transformed r_x (r_x: correlation coefficient between BMI and BAI)=1.169. r_x (correlation coefficient between BMI and BAI)=0.824. h: (1-f¹r²)/(1-r²). f=(1-r_x)/2(1-r²), f¹=(f≤1→f)(f>1→1), r²=(r₁²+r₂²)/2. N=2950.
