Note 1: The Pearson correlation coefficients presented in this row represent 13 cohorts (both Japanese and the Rome railroad cohorts were missing). The coefficients represent the relationship between serum cholesterol, total dietary fat and saturated fat intake for the 13 cohorts and CHD deaths and infarctions. Data for CHD deaths alone were not presented. Data for men without heart disease on entry were not available. The data did not compare fat/cholesterol of those with CHD versus those without. The correlations apply to fat/cholesterol data for cohorts relative to each other.
Note 2: Tertiles of cholesterol in mmol/l and number of CHD cases, not deaths, in each tertile.
Note 3: Percentage of dietary intake accounted for by total fat and number of CHD cases, not deaths, in each tertile.
*Not statistically significant.
CHD, coronary heart disease; MI, myocardial infarction; NA, data not available.
