Notes.
Data are presented as median and inter-quartile range. P values were determined by the Mann–Whitney U test and chi-square test for quantitative and qualitative data, respectively.
*
P were determined by Fisher’s Exact test for qualitative variables. Statistical significance was considered at P < 0.05.
