Angiographic analysis

	Control	Probucol	LXS	HXS
Diameter (before, mm)	2.20 ± 0.33	2.05 ± 0.33	2.22 ± 0.49	2.12 ± 0.34
Diameter (after, mm)	2.66 ± 0.34	2.49 ± 0.30	2.75 ± 0.47	2.62 ± 0.45
Diameter (follow-up, mm)	1.34 ± 0.82	1.75 ± 0.47	1.97 ± 0.51 ▲	2.03 ± 0.30 ▲
Acute gain(mm)	0.43 ± 0.17	0.51 ± 0.10	0.58 ± 0.03	0.55 ± 0.11
Late loss (mm)	1.32 ± 0.71	0.74 ± 0.39 ▲▲	0.78 ± 0.33 ▲▲	0.59 ± 0.28 ▲▲

Values are mean ± SD. No values were significantly different between groups by ANOVA (P > 0.05). ▲ P < 0.05, ▲▲ P < 0.01, significance vs. control: comparison of group means after ANOVA taking acute gain as covariance.
