title: Betaine excretion correlates with plasma homocysteine when plasma lipids are elevated.
abstract: OBJECTIVE
  To reconcile observing a positive correlation of betaine excretion with homocysteine in lipid disorder patients but not other study groups.
  
  
  METHODS
  Correlations were estimated in subgroups of a control group and the lipid disorder patients.
  
  
  RESULTS
  Plasma non high-density lipoprotein (non-HDL) cholesterol differed (p<0.0001) between the groups. The correlation increased with the median plasma non-HDL cholesterol in subgroups.
  
  
  CONCLUSIONS
  This correlation is associated with patients with elevated plasma lipids.
