Violin plots of the two groups of children were produced by t-test of operation time and postoperative hospitalization according to the actual operation laterality (unilateral or bilateral). a There was a significant difference in unilateral operation time between the two groups. ****P < 0.001. b There was a significant difference in bilateral operation time between the two groups. ****P < 0.001. c There was no significant difference in postoperative hospitalization time between the two groups after unilateral inguinal hernia repair. P = 0.418. d There was no significant difference in postoperative hospitalization time between the two groups after bilateral inguinal hernia repair. P = 0.356
