Data availability
: Look AHEAD study data are owned jointly by the individual clinical centres, the National Institutes of Health (NIH) and the coordinating centre. For approved ancillary studies and sub-studies, the Look AHEAD coordinating centre provides a cleaned data set of approved data relevant to the ancillary study. When the coordinating centre ceases to function as an analytic resource it will release all Look AHEAD data to the clinical centres and NIH. Two years subsequent to this release, the full data set will be made public. Data from the active intervention phase of the study, which ended in 2012, is available with permission through the NIH data archives (ExternalRef removed), including data from screening, baseline and follow-up for approximately 10 years.
