The Seven Countries Study was the first systematic prospective study on diet, lifestyle, risk factors and cardiovascular diseases in contrasting populations. All of the early relationships on the population level had CHD, mainly heart attacks, as endpoint. The data that came out of those early efforts were suitable for drawing conclusions on a population level. See also the cross-cultural correlations.
The predictive findings for individuals came later in the study after years of follow-up, and together provided a sound basis for preventive practice.
