SMU cohort 1 was the training cohort for developing the radiomics imaging biomarker. SMU cohort 2 and SMU cohort 3 were the internal validation cohorts. SYSUCC cohort 1 and SYSUCC cohort were the external validation cohorts. SMU cohort 4 and the GPHCM cohort were used to evaluate the of response to anti-PD-1 immunotherapy and the clinical outcomes of immunotherapy.
