‘Many factors are probably involved in the atherosclerotic development and in the clinical appearance of coronary heart disease, but there is no longer any doubt that one central item is the concentration, over time, of cholesterol and related lipids and lipoproteins in the blood serum.

(Keys, American Journal of Public Health, Nov 1953, Vol 43, pp1,399-1,407)
