All variables are expressed as the mean ± standard deviation for continuous data. Differences between the variables were compared using Fisher’s exact test or the Mann–Whitney U test. Correlation between the continuous variables was investigated using Spearman’s rank correlation coefficient. Survival curves were estimated using the Kaplan–Meier method, and the log-rank test was used to detect differences between curves. P values of < 0.05 were considered to indicate statistical significance. All statistical analyses were performed with JMP software version 14.2 for Windows (SAS Institute, Cary, NC, USA).

Continuous data are expressed as the mean ± standard deviation, and categorical data are expressed as counts, with the associated percentile value calculated. The Student t-test was used to compare continuous data, and Pearson’s χ² test was used for categorical data. A p value < 0.05 was considered to indicate statistical significance. All statistical analyses were performed with JMP software version 14.2 for Windows (SAS Institute, Cary, NC, USA).
