Statistical analyses
SPSS version 26.0 and GraphPad Prism 8.0 software were used for
statistical analyses. Quantitative data are reported as the means and
standard deviations (normal distribution) or medians and interquartile
ranges (nonnormal distribution). The T-test (normal distribution) and
Mann–Whitney U test (nonnormal distribution) were used to compare
independent samples between 2 groups. Comparisons among multiple groups
of samples were analyzed using one-way ANOVA (normal distribution) and
the Kruskal–Wallis H test (nonnormal distribution), while the
Bonferroni-corrected Mann–Whitney U test was used for intergroup
comparisons. Qualitative data are reported as frequencies and
percentages. The chi-square test or Fisher’s exact test was performed to
compare qualitative variables. The nonparametric Spearman correlation
analysis was used to analyze the correlations between two continuous
variables. A P value < 0.05 was considered
statistically significant. A receiver operating curve (ROC) was
constructed to evaluate the efficacy of the expression levels of
different molecules in predicting MG recurrence.
