2.11 Data analysis
The data was analyzed using Statistical Package for Social Sciences
(SPSS) version 25. For comparison of the measurements between the two
groups, independent samples t -test was used for the data that met
normal distribution, and the Mann-Whitney U test was used for the data
that did not meet normal distribution. Chi-square test was used for
comparison of categorical data between the groups; Pearson correlation
test was used for linear correlation analysis; Spearman correlation test
was used for rank correlation analysis; Z test was used for the
area under Receiver Operating Characteristic (ROC) curve (AUC-ROC)
comparison; multiple logistic regression was used for regression
analysis. P values of less than 0.05 were considered statistically
significant unless otherwise stated.
