Inclusion Criteria:
Serum cholesterol lowering randomized controlled trials since 1950 with publication in English that randomly assigned individual participants; provided an intervention of vegetable oil rich in linoleic acid in place of saturated fat, compared with a usual care control diet; were not confounded by the addition of large quantities of n-3 EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) or by other major concomitant interventions (such as complex changes in diet pattern) or unequal intensity of medical management (such as advice on smoking cessation or control of blood pressure); and reported deaths from coronary heart disease or all causes.
Exclusion Criteria:
Randomized controlled trials that provided large quantities of n-3 EPA and DHA or provided advice only without provision of linoleic acid rich oils from the main analysis, and studies with only biochemical or intermediate endpoints
Research Purpose:
To examine the traditional diet-heart hypothesis through recovery and analysis of previously unpublished data from the Minnesota Coronary Experiment (MCE) and to put findings in the context of existing diet-heart randomized controlled trials through a systematic review and meta-analysis.
