Figure 4.

3-node regression tree for Vaud-Fribourg men (n = 548) (gender-specific reduced {WHR, BMI} model in Table 4). Ovals: interior nodes; rectangles: terminal nodes (leaves). Numbers inside nodes are estimated mean values of TC/HDL-C (+sums of squares about the mean values). Binary classification rule: TC/HDL-C ≥ 5.0, predict dyslipidemia; TC/HDL-C < 5.0, predict no dyslipidemia).
