	BP-DES (n=304)	PF-DES (n=755)	PP-DES (n=613)	Adj. p-value
All-cause mortality	112 (41.6)	297 (43.5)	240 (42.7)	0.82
Target lesion revascularisation	60 (25.0)	161 (26.1)	127 (25.0)	0.29
Myocardial infarction	24 (8.7)	44 (6.5)	47 (8.4)	0.05
Definite or probable stent thrombosis	6 (2.0)	13 (1.8)	18 (3.3)	0.76
Data are shown as crude event rates (Kaplan-Meier estimates as percentages), p-values derived from Cox proportional hazard models. BP: biodegradable-polymer; DES: drug-eluting stent; PF: polymer-free; PP: permanent-polymer
