Data are means ± SEM. n = 6. Dietary effect (CTL versus DHA versus ALA) was compared in rats from the same dietary treatment duration and values with different letters are statistically different. a>b>c. p < 0.01. Time effect (2 months versus 6 months) was compared between rats from the same dietary group. with * = p < 0.05; ** = p < 0.01. *** = p < 0.001). Symbol $ denoted significant cross-interaction. p < 0.05.
