Text: Compared to the control period, serum phytosterol concentrations increased overall by more than 20 % when subjects consumed the plant sterol margarine (F ((1, 15)) = 8. 719, P = 0. 01), with no significant difference between heterozygotes (mean +14. 5 (s. d. 17. 2) micromol/l, +23. 0 %) and controls (+4. 9 (9. 9) micromol/l, +20. 5 % ; F ((1, 15)) = 2. 168, P = 0. 162), but decreased when subjects consumed the stanol-enriched margarine (F ((1, 15)) = 12. 124, P = 0. 003), again to a similar extent in heterozygotes (-34. 2 (41. 2) micromol/l, -54. 2 %) and controls (-12. 2 (9. 2) micromol/l, -50. 6 % ; F ((1, 15)) = 2. 729, P = 0. 119).
