A reduction in homocysteine concentration due to the use of supplemental folic acid is well recognized, although evidence same effect for natural folate sources, such as fruits and vegetables (FV), lacking. The traditional statistical analysis approaches do not provide further information. As an alternative, quantile regression allows exploration effects covariates through percentiles conditional distribution dependent variable.
