Numerical rating scale somatic pain and visceral pain scores within the first 24 h after surgery

Somatic pain scores at rest (a) and on coughing (b), and visceral pain scores at rest (c) and on coughing (d) were all significantly lower in the lateral and posterior quadratus lumborum block groups than in the control group (all P < 0.001; compared using the generalised estimating equation method). NRS, numerical rating scale; QLB, quadratus lumborum block.
