Erratum: The Diabetes Prevention Program Research Group. The 10-year cost-effectiveness of lifestyle intervention or metformin for diabetes prevention: an intent-to-treat analysis of the DPP/DPPOS (Diabetes Care (2012) 35 (723-730))

摘要

In the article listed above, an error was discovered in the calculation of the direct medical costs of inpatient care outside the DPP/ DPPOS. The costs of inpatient care were underestimated across the lifestyle, metformin, and placebo treatment groups due to delayed reporting of hospitalizations by some clinical sites and the authors' failure to count hospitalizations when the study year in which they occurred was initially unknown. The authors have now corrected this problem. In addition, they have updated the analyses to include the complete resource utilization and cost data that are newly available through 10 years of combined DPP/DPPOS follow-up. The authors have also classified participants who were diagnosed with diabetes at mid-year study visits as having diabetes during that year.
