a
Categorical variables are presented as number (%) and continuous variables as mean ± standard deviation. Categorical variables across groups were compared using Pearson's χ2 test or Fisher's exact test. Across-group comparison of means was completed using an analysis of variance. Results with P values < 0.05 were considered statistically significant.
b
