CD8A and non-small cell lung carcinoma: The higher frequency of EM CD8 T cells in cl-BAL and t-BAL remained significant compared to PB even when considering the groups of NSCLC type (cl-BAL and t-BAL vs. PB p < 0.0001, t-BAL vs. cl-BAL p = 0.5) and squamous cell carcinoma alone (t-BAL vs. PB p = 0.002; cl-BAL vs. PB p = 0.01, t-BAL vs. cl-BAL p = 0.6), which was the most common histological subtype (see Figure S3A,B).
