Table 1.
Patient characteristics according to recurrence pattern.
Table 2.
Binary logistic regression analysis comparing recurrence or metastasis within 5 years of diagnosis with no recurrence or no metastasis.
Table 3.
Binary logistic regression analysis comparing recurrence or metastasis after 5 years of diagnosis with no recurrence or no metastasis.
Figure 1.
Illustrated odds ratio in the comparison between early recurrence or metastasis within 5 years and late recurrence or metastasis after 5 years.
A binary logistic regression model was selected using Akaike Information Criteria in stepwise selection. Odds ratios are adjusted for all of the factors illustrated in the figure.
Figure 2.
Histograms of three groups based on recurrence: early recurrence within 5 years, late recurrence after 5 years, and no recurrence.
Each histogram indicates the proportion of patients with the recurrence groups in each nodal stage. Linear-by-linear association chi-squared test was performed for examination a trend between recurrence groups and nodal stage (P<0.001).

Annual recurrence rate by nodal stage.
