Figure 3 Change in numerical rating scale pain intensity following pancreatectomy stratified by quality of pain control. A: Good pain control group (n = 109, PD; n = 53, DP); B: Poor pain control group (n = 37, PD; n = 13, DP). PD: Patients underwent pancreaticoduodenectomy or pylorus-preserving pancreaticoduodenectomy; DP: Patients underwent distal pancreatectomy; POD: Postoperative day; NRS: Numerical rating scale.
