P. Jordan et al., VITAMIN-E AND VITAMIN-A CONCENTRATIONS IN PLASMA ADJUSTED FOR CHOLESTEROL AND TRIGLYCERIDES BY MULTIPLE-REGRESSION, Clinical chemistry, 41(6), 1995, pp. 924-927
The plasma concentration of vitamins A and E varies with the amount of
concurrent lipids and thus requires lipid standardization. The presen
t study compares a new multiple regression-based method for adjusting
vitamins A and E concentrations for cholesterol and triglycerides with
previous methods (adjustment for cholesterol only, and adjustment for
the sum of cholesterol and triglycerides). The results show that the
new method can reduce influence of the concurrent lipids.
