TNFRSF11B and neoplasm: The Spearman’s analysis revealed that the expression of OPG in the MGCs and the STCs was not correlated with gender, age, tumor site, Jaffe’s class or Campanicci’s class (P>0.05); however, it was negatively correlated with prognosis (rs=−0.397 and P=0.027 for MGCs; rs=−0.390 and P=0.030 for STCs).
