  1. *P-values were calculated using Cox proportional hazard analysis
  2. aCorrelation coefficients: high serum sST2 level, 1.70; blood neutrophilia, 2.94, respectively
  3. bThe cut-off value for defining blood neutrophilia was optimized using the receiver operating characteristic curve analysis and calculating the Youden index
  4. CI confidence interval
