Measure
Conventional Vitamin D Treatment
conventional vitamin D treatment: Subjects in Protocol A (the conventional/active placebo arm) received 50,000 IU/wk of vitamin D2 for 8 wk followed by 1000 IU/d of vitamin D3 for 48 wk.
Tiered/Titrated Vitamin D Dosing
tiered/titrated vitamin D dosing: Subjects in Protocol B received 2000-4000 IU/d of vitamin D3, depending on the basal 25(OH)D level, with dose titration, as necessary, based on the slope of the initial response, for a total duration of treatment of 12 mo.
