Lipid parameters
Non-HDLc	137.82 (38.22)	136.62 (38.90)	142.33 (43.41)	N.S.
TC/HDLc	4.25 (1.31)	4.28 (1.25)	4.53 (1.35)	0.097
LDL/HDLc	2.62 (1.06)	2.65 (0.99)	2.81 (1.10)	0.200
apoB/apoA	0.75 (0.25)	0.78 (0.25)	0.81 (0.26)	0.073

Group A: patients with stenosis ≥ 50% in a vessel; Group B: patients with stenosis ≥ 50% in two vessels; Group C: patients with stenosis ≥ 50% in three vessels; HDLc: high-density lipoprotein cholesterol; LDLc: low-density lipoprotein cholesterol. Quantitative variables are expressed as percentages; Pearson Chi-square was used to determine 𝑃 values; quantitative variables are expressed as mean (standard deviation), 𝑃 values were determined by ANOVA test.
