Table 3. Multiple Cox regression models for the association between multi-vessel disease and 1 and 3-year outcomes (excluding first 30 days post-PPCI.

1-year Outcome	Unadjusted HR [95%] CI, P value	Adjusted* HR [95%] CI, P value
Mortality	N/A**	N/A**
Re-infarction	1.5 [0.52–4.38], P = 0.44	1.83 [0.62–5.4], P = 0.27
Revascularization	0.94 [0.52–1.68], P = 0.83	1.15 [0.63–2.1], P = 0.65
MACE	1.5 [0.88–2.65], P = 0.12	1.27 [0.71–2.23], P = 0.42
3-year Outcome	Unadjusted HR [95%] CI, P value	Adjusted* HR [95%] CI, P value
Mortality	1.03 [0.51–2.08], P = 0.92	0.74 [0.33–1.65], P = 0.46

* Adjusted for age, sex, glomerular filtration rate, diabetes mellitus, left anterior descending artery disease, pre-TIMI flow grade<2 and left ventricle ejection fraction

** No mortality events in the multi-vessel group

CI = Confidence interval; HR = Hazard ratio; MACE = Major adverse cardiac events
