Categorical valuables were analyzed via the Wilcoxon signed‐rank test. Statistical significance was considered as P < 0.05. All analyses were conducted using R language and environment for statistical computing (version 3.5.2, R Core Team, 2018, R Foundation for Statistical Computing, Vienna, Austria).
