Trial overview
Official title: AVANDIA CV Outcomes Study: Thiazolidinedione Intervention with vitamin D Evaluation (TIDE) A Multicenter Randomized Double-Blind Placebo-Controlled Trial of a Thiazolidinedione or Placebo and of Vitamin D or Placebo In People With Type 2 Diabetes at Risk For Cardiovascular Disease
Trial description: This study will answer two separate questions. The first question is to test the cardiovascular effects of long-term treatment with rosiglitazone or pioglitazone when used as part of standard of care compared to similar standard of care without rosiglitazone or pioglitazone in patients with type 2 diabetes who have a history of or are at risk for cardiovascular disease. The second question will compare the effects of long-term supplementation of vitamin D on death and cancer
