BLINDNESS
The patients, who were included in the study, were divided randomly into Group M-TAPA and Group OSTAP according to the computerized randomization table created by a researcher who was not involved in the study. A random code was assigned to each patient, who participated in the study, to ensure blindness, and each code was placed in sealed envelopes. The surgery room anesthetist took from a file the corresponding sealed envelope indicating the block to be performed for each randomized patient.Block applications were performed in both groups following routine anesthesia induction and patient intubation. (Supplementary Fig. Surgeons and surgery room anesthetists were not included in any postoperative stage, including data collection, data access, and data analysis. The researchers who were interested in recording postoperative parameters were masked in the distribution of patient groups and did not have access to randomization until data analysis was complete.
