MLN, metastatic lymph node; LNR, lymph node ratio; LODDS, log ratio of metastatic lymph node; C-index, concordance index.
a: Comparison of OS rates within different LNR subgroups. Bold P values have statistical significance (i.e., P < 0.05)
b: Comparison of OS rates within different MLN subgroups. Bold P values have statistical significance (i.e., P < 0.05)
c: Comparison of OS rates within different LODDS subgroups. Bold P values have statistical significance (i.e., P < 0.05)
