what's the mechanism by which niacin raised HDL cholesterol I think one is certainly triglyceride lowering like we were talking about earlier but probably not just that because the increases in HDO were somewhat disproportionate to what you'd predict from the triglyceride lowering although again with the complexity it's a little hard to make that calculation so there probably is some other mechanism and to this day I don't think we really understand it
