Table 3 Predictors of 1 and 3 years mortality by forward conditional Cox proportional hazard analysis.

From: The importance of left ventricular function for long-term outcome after primary percutaneous coronary intervention

1 year mortality     
Characteristics Hazard ratio 95% CI Wald χ2 p
Age, per 10 years 2.01 1.33 – 3.03 11.1 0.001
LVEF, per 5 % decreasing 1.44 1.23 – 1.69 20.4 < 0.001
3 year mortality     
Characteristics Hazard ratio 95% CI Wald χ2 p
Age, per 10 years 1.64 1.25 – 2.15 12.6 < 0.001
LVEF, per 5 % decreasing 1.28 1.14 – 1.44 17.6 < 0.001
