%BF, body fat percentage; LHR, likelihood ratio; pos, positive; neg, negative; HOMA-IR, homeostasis model assessment–insulin resistance index; TC, total cholesterol; HDL-C, HDL-cholesterol.
*
For each %BF demarcation range, adverse CVD risk profile is defined as HOMA-IR ≥ 3·16 and/or TC:HDL-C ≥ 4·5.
