  1. Differences between mean serum lipid levels were estimated with the t test. P values < 0.05 were considered statistical significant (bold). All models are weighted population estimates: standardized to population structure as of 31st December 2010
  2. aAdjusted for age
  3. bAdjusted for age, educational status, current smoking, coffee consumption, processed food consumption, wholegrain bread consumption, high alcohol consumption, sports activity, body mass index category, use of lipid-lowering medication, hormonal contraceptives, and postmenopausal hormone therapy
  4. cAdditionally adjusted for fasting duration
