Values are presented as frequency (%) or mean ± standard deviation.
Bonferroni correction was used for multiple comparisons.
IV-PCA: intravenous patient-controlled analgesia, ESPB: erector spinae plane block, NRS: numeric rating score.
Each item except for presence of pain is rated on NRS (from ‘0’ = [no pain] to ‘10’ [worst] or as ‘0’ [no interference] to ‘10’ [interferes completely]).
