Figure 3

Forest plot demonstrating predictive value of biomarkers and ECG for all-cause mortality and hospital length of stay. Cox multivariable proportional hazards model, adjusted for demographic and clinical covariates, is shown for each individual variable. HRs and 95% CIs are shown. All biomarkers were entered as continuous variables. Significances for mortality: POD1 cTnI (HR 1.42 for each 10 µg/L increase; 95% CI 1.14–1.76; P = 0.009), POD1 CKMB (HR 1.23 for each 25 µg/L increase; 95% CI 1.02–1.48; P = 0.034) Significances for HLOS: POD1 cTnI (HR 1.13 for each 10 µg/L increase, 95% CI 1.02–1.26; P = 0.011), POD1 CKMB (HR 1.06 for each 25 µg/L increase, 95% CI 1.01–1.12; P = 0.01) HR indicates hazard ratio; CI, confidence interval; CKMB creatinine kinase MB fraction; cTnI, cardiac troponin I; POD, post-operative day; ECG, electrocardiogram.
