CD8A and hip fracture: There was also a trend towards an accumulation of KLRG1+ve T cells in hip fracture patients with higher GDS scores, but this did not reach statistical significance for the frequency of KLRG1+ve CD4 T cells, r (39) = .29, p = .06, or KLRG1+ve CD8 T cells, r (39) = .28, p = .07.
