Different models to evaluate association of lipoprotein(a) with recurrent cardiovascular events

Model	LP(a) as a nominal variablea			LP(a) as a continuous variableb
	HR	95% CI	P value	HR	95% CI	P value
Crude model	1.819	1.241–2.666	0.002	1.255	1.094–1.439	0.001
Model 1	1.850	1.262–2.713	0.002	1.264	1.100–1.453	<0.001
Model 2	1.937	1.313–2.856	<0.001	1.280	1.115–1.470	<0.001
Model 3	2.068	1.366–3132	<0.001	1.285	1.112–1.484	<0.001

Model 1: adjusted for age, sex and type of ACS.

Model 2: adjusted for variables in model 1 and smoking, diabetes and hypertension.

Model 3: adjusted for variables in model 2 and LDL-C, serum creatinine and PCI.

ACS, acute coronary syndrome; CI, confidence interval; HR, hazard ratio; Lp(a), lipoprotein(a); PCI, percutaneous coronary intervention.

^aThe HR was examined regarding low-Lp(a) group as reference.

^bThe HR was examined by per 1-SD increase of Lp(a).
