Comparative analysis of T lymphocyte subsets and CD4/8 ratio in newly-diagnosed follicular lymphoma (ND-FL) patients and healthy controls (HCs): (A) CD3 + T cells, (B) CD4 + T cells, (C) CD8 + T cells, and (D) CD4/8 ratio. Statistically significant differences were indicated as * P < 0.05, ** P < 0.01, ***P < 0.001, ****P < 0.0001. The association of baseline T cell subsets with patient characteristics was also shown, including (E) age, (F) histological grade, (G) Ann Arbor Stage, and (H) bone marrow involvement (BMI). Further analyses were conducted to explore the relationship between FLIPI score and CD3 + T cells (I), CD4 + T cells (J), CD8 + T cells (K), and CD4/8 ratio (L).
