CD19 and hip fracture: Similarly, significant differences were seen in absolute numbers of CD19+CD24hiCD38hi B cells, F (2, 38) = 4.85, p = .01, η2 = .20 (Fig. 3b) between our three groups, driven by a significant decline in absolute numbers in hip fracture patients with depressive symptoms compared with healthy controls, p = .04 as well as hip fracture patients without depressive symptoms, p = .02.
