Patients’ baseline characteristics and surgery description for three groups after 1:1:1 propensity score matching.
The three groups are patients who received TAP infiltration, Epidural, or IV PCA.

Results for comparison TAP infiltration and Epidural patients on postoperative time-weighted average pain score in the 0–10 NRS pain scale and intravenous morphine equivalent dose of opioid within 72 hours of the surgery.
Fig 4.
Results for two comparisons including TAP infiltration versus intravenous patient-controlled analgesia (IV PCA) and Epidural versus IV PCA on postoperative time-weighted average pain score in the 0–10 NRS pain scale and intravenous morphine equivalent dose of opioid within 72 hours of the surgery.

Results for the primary outcomes on matched patients.
Observed outcomes are reported as, median [1st quartile, 3rd quartile] or ‘mean ± standard deviation’.
