Kaplan-Meier survival curve representing the time to first opioid administration. P=0.041 comparing all groups using a global test; P=0.015 between the CTEB group and TPVB group; P=0.039 between the ESPB group and TPVB group. There was no significant difference between the CTEB group and ESPB group (P=0.805). CTEB – combined thoracic paravertebral block and erector spinae plane block; ESPB – erector spinae plane block; TPVB – thoracic paravertebral block.
