Association between log sRANKL/OPG ratio and extent of bone disease as assessed by radiographic evaluation. Median values (ranges) of the sRANKL/OPG ratio for controls and patients were as follows: controls, 0.33 (0.10-0.59); group A (no lytic lesions or osteoporosis), 0.57 (0.10-1.01); group B (1-3 lytic lesions), 0.84 (0.26-4.16); group C (more than 3 lytic lesions or fractures), 2.25 (0.43-44.04). Circled numbers referred to patient outliers.
