TNFRSF11B and type 1 diabetes mellitus: Table 2). No statistically significant difference in OPG or sRANKL levels was observed between the two subgroups of patients with T1DM. Patients in the subgroup with longer diabetes duration were indicatively older and had higher triglyceride levels (P-value 0.025) and higher BMI (P-value 0.044), but similar glycaemic control (HbA1c P-value 0.133), when compared to the subgroup of T1DM patients with shorter diabetes duration.
