Many discrepancies with the primary publications were found. First, 4 eligible studies, including the Framingham Offspring Study,2 were not included. Second, 5 studies did not meet the entry criteria, which included approved definitions and recording of both fatal and nonfatal cardiovascular events. The Whitehall I study3 recorded only fatal ischemic heart disease and so should not have been eligible. Yet strokes were listed in eTable 1 even though they were not a protocol outcome. Third, in 19 of the 26 studies, the number of participants differed substantially between eTable 1 and the primary publication. In 14 studies, there were fewer participants whereas in 5 studies, there were more participants. For example, the ERFC study listed 1293 patients for the Quebec Cardiovascular Study vs the actual tally of 2072.4 The ERFC study listed 23 175 for the Women's Health Study vs 15 632 in the primary report.5 Fourth, the values for apolipoprotein B in 4 study reports differed substantially from those given by the ERFC and neither the methods to measure apolipoprotein B nor the results were given in 4 other studies. Furthermore, in at least 2 studies, apolipoprotein B was measured many years after collection with no documentation of adequate sample preservation. Fifth, the methods and results of 11 studies have not been recorded in the public domain.
