Serum cholesterol response to dietary cholesterol

Serum cholesterol change, ΔChol mg/dl, from change only in dietary cholesterol, mg/1,000 kcal, x, was analyzed with data from 39 controlled experiments on 64 adults with the model ΔChol = b(x2k − x1k). Values of b were found by iteration for exponents k = 0.3 to k = i.0 yielding eight regression equations to check predicted against observed. The smallest root mean square deviation from regression was 7 mg/dl given by ΔChol = 1.5(x2½ − x1½) which...
