Figure 2. Correlation between serum levels of (a) osteopontin and bone-specific alkaline phosphatase, (b) osteopontin and current disease extent, (c) bone-specific alkaline phosphatase and current disease extent, (d) RANKL and current disease extent and (e) RANKL and bone-specific alkaline phosphatase in 57 patients with PDB. Each point represents the results of an individual patient. Lines represent results of regressions: linear, logarithmic or exponential.
