However the frequency of CD19+CD24hiCD38hi B cells in the B cell pool differed between our three groups, F(2, 61) = 11.16, p < .001, η2 = .26 (Fig. 3a), due to a decline in this subset in hip fracture patients with depressive symptoms compared with healthy controls, p < .001 as well as hip fracture patients without depressive symptoms, p = .001. This evidence concerns the gene CD19 and hip fracture.
