In a 2004 Cochrane review, the same authors concluded that there was a significant beneficial effect on total mortality, combined cardiovascular endpoints and cancer. Inclusion of the recent 'Diet and reinfarction trial' (DART-2-trial) had a decisive negative effect on the results of the recent meta-analysis.
