Study Arms:
- pioglitazone (Type: ACTIVE_COMPARATOR): PIO tablet was administered in the dose of 30 milligrams (mg) OD initially and could be titrated to a maximum dose of 45 mg at or after the 6-month visit. After 1 year of treatment, the dose of PIO was increased to 45 mg OD for the duration of 5.5 years.
- rosiglitazone (Type: ACTIVE_COMPARATOR): RSG tablet was administered in the dose of 4 mg OD initially and could be titrated to a maximum dose of 8 mg at or after the 6-month visit. After 1 year of treatment, the dose of RSG was increased to 8 mg OD for the duration of 5.5 years.
- TZD placebo (Type: PLACEBO_COMPARATOR): Matching placebo tablet was administered once a day (OD) for the duration of 5.5 years
- Vitamin D (Type: ACTIVE_COMPARATOR): Active comparator
- Vitamin D placebo (Type: PLACEBO_COMPARATOR): Placebo Comparator
