significant difference between groups B2 and C; △, no significant difference between groups B2 and C; ●, significant difference between groups B1 and C; ○, no significant difference between groups B1 and C.
The difference between groups was considered to be significant if P < .05. Nine features show significant difference between subgroup B2 and group C and no significant difference between subgroup B1 and group C (indicated by ▲ and ○). Only one feature shows the opposite result (indicated by △ and ●).
