Statistical Analysis
Baseline characteristics were compared using student’s t test or Wilcoxon test for continuous variables or the chi-square test for categorical variables between the ICM and DCM groups. The cumulative risks of all-cause death were estimated using the Kaplan-Meier method and the use of the log-rank test. Analysis was performed with SPSS Statistics software (version 26) and the variables were presented as number or mean ± standard deviation, as appropriate. When two-sided P value <0.05, the difference considered statistically significant.
