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