Bone turnover factors and Wnt signaling antagonists in patients with OYL and controls. Serum levels of OSC (*p < 0.05) were higher but those of DKK-1 (**p < 0.01) were lower in the patients with OYL than in the controls. No significant differences in SFRP-1, SOST and OPG levels in the OYL patients and controls were detected. (OSC, SFRP-1, OPG: ng/mL; Dkk-1, SOST: pg/mL)
