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.
