CETP and coronary artery disorder: To further evaluate the associations of preβ1-HDL and CETP with the severity of CAD in ACS or SCAD patients, preβ1-HDL (OR = 1.017, 95% CI: 1.003–1.031, P = 0.016) and CETP (OR = 1.931, 95%CI: 1.456–2.563, P < 0.001) were found closely associated with ACS group when treated the SCAD group as the reference category.
