a AUCs of the receiver operating characteristic curves of the radiomics imaging biomarker comparing the NLR-H group to the NLR-L group in each cohort. b AUCs of the receiver operating characteristic curves of the radiomics imaging biomarker comparing the NLR-H group to the combination of the NLR-L and NLR-M groups in each cohort. c Radiomics score of different NLR statuses in the training cohort (NLR-L: n = 80; NLR-M: n = 80; NLR-H: n = 80), internal validation cohort 1 (NLR-L: n = 56; NLR-M: n = 43, NLR-H: n = 59), and external validation cohort 1 (NLR-L: n = 37; NLR-M: n = 27; NLR-H: n = 28). The data are presented as the mean values with SEM. For statistical comparisons among different groups, a two-tailed t test (unpaired) was used. NLR-H: NLR-High group, NLR-M: NLR-Mix group, NLR-L: NLR-Low group. Source data are provided as a Source data file.
