Methods I
Parallel, randomized, placebo-controlled study
N=150, mildly hypercholesterolaemic (5,2–6,4 mmol/l) subjects 4-week run-in with a NCEP Step I diet, intervention for 16 weeks
Placebo spread; NCEP Step I diet Plant stanol ester containing spread (2 g plant
stanols/d); NCEP Step I diet Mediterranean diet

Athyros et al. Nutr Metab Cardiovasc Dis 2011. 3
Methods II
Outcome measures:
Individual risk factors: changes in lipids and lipoproteins (TC, LDL-C, HDL-C,
TG, apo B, apo A1) blood pressure haemostatic factors (plasma fibrinogen & PAI-1
activity) inflammatory marker (hsCRP)
Estimated CVD risk (Framingham, PROCAM & Raynolds risk engines)
Percentage of patients at NCEP Total Cholesterol target (< 5.2 mmol/l)

Results I
Effect of intervention on risk factors:
Placebo: no significant effect on any of the risk factors
Plant stanol ester: TC ↓, LDL ↓ and hsCRP ↓ (statistically significant change in all)
Mediterranean diet: TC ↓, LDL ↓, TG ↓, blood pressure ↓, hsCRP and thrombotic markers ↓; HDL ↑(statistically significant change in all)

Results II
Estimated cardiovascular disease risk:
• Placebo: no effect on estimated disease risk
• Plant stanol ester: eCVD risk reduction of 26–30 % in 1 month with all risk engines used, sustained the 4 months intervention
• Mediterranean diet: eCVD risk reduction of 24–32% in 4 months with all risk engines used

Results III
Percentage of subjects meeting target level for total cholesterol (<5.2 mmol/L) by the end of the study:
• Placebo: 14 %• Plant stanol ester: 80 %• Mediterranean diet: 46 %

Conclusions
Mediterranean diet was efficient in reducing the estimated CVD risk by several mechanisms but the change was fully seen only after 4 months
Plant stanol ester reduced the estimated risk of CVD as effectively already after 1 month
The use of plant stanol ester products is especially beneficial for those individuals who are unable to adopt Mediterranean diet
