Linear logistic regression analysis (standardized partial regression coefficient Beta and p-value) of the independent predictive character of the covariables age, gender, plasma folate level, and plasma vitamin B12 level for the dependent variables triglycerides, HDL-C, LDL-C, LDL-C/HDL-C-ratio and total cholesterol levels are depicted. As these were five separate analyses, we set the level of significance to alpha = 0.01
