Fig. 3From: Free vitamin D correlate better with bone mineral density and thoracolumbar junction osteoporotic vertebral fractures than serum vitamin DScatter plots of total and free 25(OH) D concentrations plotted against different fracture parameters; (a) presence of fracture (b) fracture grade c) occurrence of fracture. Free vitamin D concentration was considerably lower in patients with OVFs than in patients without OVFs. The black bars indicate mean and standard deviation. *p < 0.05.
