Frequency of peripheral T lymphocytes in hip fracture patients with and without depressive symptoms versus healthy controls. (a) The percentage of CD3^+ve T cells in healthy controls: n = 37; hip fracture patients without depression (HF): n = 38 and hip fracture patients with depressive symptoms (HF + D): n = 29.The solid bar represents the mean value. (b) The mean absolute number of T cells in healthy controls: n = 20; hip fracture patients without depression (HF): n = 19 and hip fracture patients with depressive symptoms (HF + D): n = 15. Data are mean ± SEM. *p < .05 and **p < .01. Representative flow cytometry plots and gating strategy of PBMCs from a young individual stained with anti-CD3 and (c) anti-CD4, and CD8, (d) and anti-CD45RA and -CCR7 (e and f).
