Values are presented as numbers (%), , and median (interquartile range). Fisher’s exact test was used for categorical variables, while Student’s test and Mann–Whitney test were used for continuous variables. SD: standard deviation; IQR: interquartile range; HPLC: high-performance liquid chromatography.
