On comparing the frequency of IL6+ve CD4 T cells [Figure 5c] post-stimulation with PMA and Ionomycin, significant differences were found between our three groups F (2, 57) = 3.47, p = .03, η2 = .10, driven by an increase in percentage of IL6+ve CD4 T cells in hip fracture patients with depressive symptoms compared with healthy controls, p = .04, no significant differences were observed between hip fracture patients with and without depressive symptoms, p = .17 [Figure 5d]. The gene discussed is IL6; the disease is hip fracture.
