IRLS is an independent prognosis factor in the nomogram. a, b Forest plot summary of the univariate and multivariable Cox analyses of the IRLS and clinicopathological characteristics. The blue diamond squares on the transverse lines indicate the HR, and the black transverse lines indicate the 95% CI. c Nomograms integrating the IRLS and pathology N stage for predicting the probability of patient mortality at 3- or 5-year OS. d, e Calibration curves of the nomogram for predicting the survival outcomes at 3-, and 5-years.The 45-degree line represents the ideal prediction. f–g Decision curve analyses (DCA) curve of the nomograms for 3-year and 5-year OS
