From: Modelling the probability of erroneous negative lymph node staging in patients with colon cancer
Disease-free survival according to final error probability (low-, intermediate- or high-risk groups) and pN stage (pN+ , pN1 or pN2). a Disease-free survival of low-, intermediate- and high-risk groups, and pN+ group. b Disease-free survival of low-, intermediate- and high-risk groups, pN1 and pN2 groups. P values obtained by log-rank test were summarized in the tables below
