Postoperative NRS scores at rest and on movement in the first 24 hours

Outcomes	IV-PCA alone (n = 29)	IV-PCA plus ESPB (n = 29)	P value
NRS at rest
3 hours	3 (2-4)	3 (1-4)	0.648
6 hours	3 (3-4)	3 (2-4)	0.632
9 hours	3 (2-6)	3 (1-4)	0.888
24 hours	2 (2-4)	2 (1-3)	> 0.999
NRS on movement
3 hours	6 (4-7)	4 (3-5)	0.552
6 hours	7 (5-8)	5 (3-7)	0.212
9 hours	7 (5-10)	5 (4-7)	0.716
24 hours	5 (4-7)	4 (3-6)	0.120

Values are presented as median (interquartile range).

Bonferroni correction was used for multiple comparisons.

NRS: numeric rating score, IV-PCA: intravenous patient-controlled analgesia, ESPB: erector spinae plane block.
