In women, the node purity scores from the Random Forest analysis revealed the following results based on biochemical data for identifying CHD cases: (1) preβ-1 HDL 0.350, (2) α-2 HDL 0.151, (3) sdLDL-C 0.131, (4) log MPO 0.130, (5) α-3 HDL 0.047, (6) α-1 HDL 0.035, (7) uric acid 0.035, (8) log CRP 0.0228), (9) creatinine 0.027, (10) α-4 HDL 0.022, (11) log Lp(a) 0.020, and (12) log TG 0.018. Here, MPO is linked to coronary artery disorder.
