Effect of Simvastatin and Atorvastatin on Serum Vitamin D and Bone Mineral Density in Hypercholesterolemic Patients: A Cross-Sectional Study

Table 4

Results of serum 25-hydroxyvitamin D, lumbar spine BMD, and femoral neck BMD in the study and control groups with regard to supplementation. CI: confidence interval; 25OHD: 25-hydroxyvitamin D; BMD: bone mineral density. Supplementation is in the form of calcium and vitamin D.
