Patients were treated with protocols VD and serum Vit D was measured at baseline and after 6 weeks. Paired t-test was used to calculate the difference within groups. Error bars represent SEM. ****P < 0.0001. b. Patients were treated with protocols H + S and serum Vit D was measured at baseline and after 6 weeks of treatment. c. Patients were treated with protocols VD + H + S and serum Vit D was measured at baseline and after 6 weeks of treatment. The arrow depicts the patient that developed hypercalcemia. d. Vit D levels in controls subjects. Paired t-test was used to calculate the difference within groups. Error bars represent SEM. **P < 0.01; ****P < 0.0001.
