Receiver operator characteristic curve analysis for the test and validation cohorts. The receiver operator characteristic curve analysis for the (A) test and (B) validation cohorts shows the ability of the different models to discriminate for overall survival. The models tested in addition to the RMH score alone and the NLR alone were RMH score+NLR50 and RMH score+Log₁₀NLR, as they were found to be significantly associated with overall survival in multivariate analysis. Abbreviations: NLR=Neutrophil–lymphocyte ratio; RMH=Royal Marsden Hospital Score.
