RT Journal A1 Sheehe PR T1 COmposite end points in clinical trials JF JAMA JO JAMA YR 2010 FD May 5 VO 303 IS 17 SP 1698 OP 1698 DO 10.1001/jama.2010.522 UL http://dx.doi.org/10.1001/jama.2010.522 AB To the Editor: In their Commentary on the use of composite end points in clinical trials, Drs Tomlinson and Detsky1 asked why the clinical trial of rosiglitazone2 used the primary outcome of diabetes or death. Although the authors discussed various (often problematic) reasons for using composite end points, they did not consider an important legitimate reason for combining death with another end event: to focus on the long-term risk of the end point.
