Comparison of angina score between groups at baseline and after treatment.

Total Angina Score, median (IQR)	Experimental group: Statin + STS (n = 35)	Control group: Statin (n = 35)	P value
Baseline	10 (6, 12)	12 (8, 14)	0.105
After 14-day treatment	0 (0, 6)	6 (0, 10)	0.00
30 days after treatment completion	2 (0, 8)	8 (6, 10)	0.00

IQR, interquartile range; STS, sodium tanshinone IIA sulfate. Inter-group comparison was analyzed using the Wilcoxon rank-sum test, due to non-normal distribution of the data.
