ND, not determined.

Mean value was significantly different from that at baseline: * P ≤ 0·05, ** P ≤ 0·01.

^†Ahiflower oil v. flax seed oil at 28 d.

^‡This P value is not associated with a time × treatment effect, it is rather associated with the effect of oil on the difference between values at baseline and at 28 d.

^§Statistical results are not reported because the heteroscedasticity structure could not be modelled.
