Table 4 Association of tumor diameter with pT and pN classifications in rectal cancer- validation cohort (n = 28)

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 7 (77.8) 5 (26.3) 9.8 (1.5-64) 0.017 0.73
  pT3-4 2 (22.2) 14 (73.7)    
   ≤ 29 mm >29 mm    
pN classification pN0 3 (75.0) 12 (50.0) 3.0 (0.3-33.1) 0.37 0.56
  pN1-2 1 (25.0) 12 (50.0)    
  1. OR: odds ratio. AUC: area under the ROC curve, illustrating discriminatory ability of tumor size for pT and pN classifications
