  2. Data on published ACTG clinical trials that do not appear on this list are available by sending an email to Please provide: full names and contact information for collaborators; a brief statement of the objectives of the project; the ACTG protocol numbers of the studies (or, alternatively, publication references for the studies) from which data are being requested; and the variables and, where relevant, the time points for the variables that are being requested.
