Figure 1: An immunoassay of the T cell subsets before and after hydrogen inhalation in non-small cell lung cancer patients. Note: (A) Test results of the CD4+ subsets. (B) Test results of the CD8+ subsets. (C) Test results of the cytokine-secreting CD4+ subsets. The parallel red long lines in the figure represent the normal range, the black short lines represent the average value at each time point, and the pink cell names represent the abnormal indicators before hydrogen treatment. Data were analyzed by repeated measures analysis of variance followed by Bonferroni’s multiple comparison test. *P < 0.05. CXCR5: C-X-C chemokine receptor type 5; Th: helper T; Tfh: follicular helper T.
