Models	HRa	95 % CI	Chi-square	p value
Univariable model of HSP70 (high vs. low)	1.712	1.174–2.496	7.877	0.005
Multivariable model of HSP70 (high vs. low) adjusted for age, sex, BMI, serum creatinine and NT-proBNP	1.556	1.042–2.325	4.654	0.031
Multivariable model of HSP70 (high vs. low) adjusted for age, sex, BMI, serum creatinine and left ventricular EF	1.590	1.046–2.417	4.720	0.030

HR hazard ratio

^aHSP70 as a categorical variable, stratified according to the median level (HR for comparison of patients with high vs. low HSP70 level) with 95 % CI; Wald chi-square and p values of likelihood ratio tests are presented
