- Comparison of post-procedure complication rates and radiology doctor satisfaction levels between groups (N=15).

Variables	Group control	Group ESPB	P-value
Postoperative complications, n (%)
Yes	1 (6.7)	0 (0.0)	0.999
No	14 (93.3)	15 (100.0)	0.999
Radiology doctor satisfaction score
Not satisfied at all	1 (6.7)^a	0 (0.0)^a	<0.001
Not satisfied	7 (46.7)^a	0 (0.0)b
Reasonable	6 (40.0)^a	2 (13.3)^a
Satisfied	1 (6.7)^a	4 (26.7)^a
Excellent	0 (0.0)^a	9 (60.0)^b

Superscripts a and b indicate the difference between groups in each category. Groups with the same letters in each category were statistically similar. ESPB: erector spinae plane block
