Indices of hepatic steatosis and fibrosis in prediabetes and association with diabetes development in the vitamin D and type 2 diabetes study

The conduct of the trial was supported primarily by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) and the Office of Dietary Supplements of the National Institutes of Health through the multicenter clinical study cooperative agreement (U01DK098245; principal investigator, Dr. Pittas) to Tufts Medical Center, where the D2d Coordinating Center is based. The U01 grant mechanism establishes the NIDDK project scientist (Dr. Staten) as a member of the D2d Research Group. The trial also received secondary funding from the American Diabetes Association to Tufts Medical Center (1-14-D2d-01; principal investigator, Dr. Pittas). Dr. Pittas is supported in part by generous donations to the Tupper Research Fund at Tufts Medical Center. Neither the funders nor the author's institutions had any role in study design; collection, analysis, and interpretation of data; writing the report; and the decision to submit the report for publication.
