Analysis of the correlations between γδT17 cells and OS in older-aged LUAD and LUSC patients versus the younger-aged patients

Patients were divided into high (≥ 3.1 cells/mm² in LUAD and ≥ 2.5 cells/mm² in LUSC) and low (< 3.1 cells/mm² in LUAD and < 2.5 cells/mm² in LUSC) groups based on the levels of γδT 17 cells using cutoff values calculated by receiver operating characteristic curves. Parson’s χ² test was used. *p<0.05, **p<0.01. OS, overall survival
