Prognostic analyses for 
REGRESSION
The detailed results of the univariate Cox regression analyses in training cohort are demonstrated in Table Univariate Cox regression analyses for predicting OS and CSS in training cohortAbbreviations: CI, confidence interval; CSS, cause‐specific survival; HR, hazard ratio; LNR, lymph node ratio; LODDS, log odds of positive lymph node; OS, overall survival; PLN, positive lymph node.Represented We further performed multivariate analyses and generated prognostic models including different LN indicators, respectively. Briefly, N classification, PLN, LNR and LODDS were all independent risk factors for OS (Table Multivariate Cox regression analyses for predicting OS in training cohortAbbreviations: CI, confidence interval; HR, hazard ratio; LNR, lymph node ratio; LODDS, log odds of positive lymph node; OS, overall survival; PLN, positive lymph node.Represented Multivariate Cox regression analyses for predicting CSS in training cohortAbbreviations: CI, confidence interval; CSS, cause‐specific survival; HR, hazard ratio; LNR, lymph node ratio; LODDS, log odds of positive lymph node; PLN, positive lymph node.Represented
