Complications among the studied groups.

Complications	FICB (N = 64)	QLB (N = 64)	^§ value	Effect size; Relative risk; 95% CI
Subcutaneous collection	1 (1.6%)	1 (1.6%)	0.999	1.00 (0.06–15.64)
Bad separation of fascia	1 (1.6%)	0 (0.0%)	0.999	Not applicable
Hypotension	0 (0.0%)	1 (1.6%)	0.999	Not applicable

^§Fisher’s exact test. Effect size: value of FICB relative to QLB. CI, confidence interval.
