Table 1. Kaplan-Meier estimates of pooled ischaemic and bleeding event rates in the five included studies.

Variable		Number of events	Rate	p-value (0-1 vs 1-3 years)
Myocardial infarction	0-1 year	150	5.1%	0.01
	1-3 years	102	3.6%
	0-3 years	238	8.2%
Scaffold thrombosis	0-1 year	36	1.2%	0.80
	1-3 years	31	1.1%
	0-3 years	67	2.3%
Bleeding	0-1 year	25	0.8%	0.15
	1-3 years	29	1.0%
	0-3 years	53	1.8%
Death	0-1 year	25	0.8%	<0.0001
	1-3 years	57	2.0%
	0-3 years	82	2.9%
Landmark analysis: patients can have events (except death) in both time periods (0-1 year and 1-3 years), which explains why the sum of the numbers of events (and incidence rates) for the two periods can be greater than the total between 0 and 3 years.
