In the 2nd batch, PZP (1.36, 1.20–1.54), COCH (1.36, 1.21–1.52) and B2M (1.32, 1.20–0.46) were the top three positively associated proteins with IHD, while MXRA8 (0.80, 0.71–0.91) and CBLN1 (0.80, 0.72–0.92) were the top two inversely associated proteins with IHD. Here, CBLN1 is linked to myocardial ischemia.
