Randomization and blinding
Patients were randomly allocated to either the TFB or QLB group, in a ratio of 1:1 using SPSS 28 software (Statistical Program for Social Sciences, SPSS Inc., Chicago, Illinois, USA) by a physician who was not involved in the data analysis. Patients group assignments were placed in closed, opaque, sealed and sequentially numbered envelops that were opened in the operating room before induction of anesthesia. Ultrasound-guided TFB or QLB were performed by a single anesthesiologist who have good experience in the ultrasound-guided nerve blocks and was not involved in any other related process according to the patient group allocation. Patients, anesthesiologist who was responsible for patients, surgeon, and physician who was responsible for the postoperative care, all were blinded to patient group allocation.
