From: Role of tumor size in the pre-operative management of rectal cancer patients

   Frequency N (%) OR (95%CI) P-value AUC
   ≤ 34 mm >34 mm    
pT classification pT1-2 31 (67.4) 88 (23.7) 6.67 (3.4-12.9) <0.001 0.66
  pT3-4 15 (32.6) 284 (76.3)    
   ≤ 29 mm >29 mm    
pN classification pN0 35 (15.5) 11 (5.7) 3.02 (1.5-6.1) 0.002 0.55
  pN1-2 191 (84.5) 181 (94.3)    
  1. OR: odds ratio. AUC: area under the ROC curve, illustrating discriminatory ability of tumor size for pT and pN classifications
