Population based randomised controlled trial on impact of screening on mortality from abdominal aortic aneurysm

Tables 2 and 3 of both the abridged and the full versions of this paper by Paul E Norman and colleagues contain some incorrect values (BMJ 2004;329:1259-62). In table 2, for the emergency procedures the “all ruptures” values are 19 and 22 for the “not scanned” and “total invited” groups respectively and 27 in the control group; in table 3, the corresponding values are 32, 35, and 38. The authors state, however, that this amendment does not alter their analyses or conclusions.
