Figure 1 –Cox Proportional Hazard Model for Daily Probability of Discharge vs Time (days) following surgery. A. Subjects with abnormal (blue) vs. normal (red) left ventricular performance during diastole. B. Dose-response relationship between severity of performance abnormality during diastole and daily probability of discharge; mild dysfunction (green), moderate dysfunction (blue), severe dysfunction (purple), normal (red). Survival analyses performed using R programming environment. Estimates and CIs obtained using the “coxph”function.
