¹ Portions of the respective fatty acid in % of total FAME as mean ± SD of high dairy fat intake (> 40 g/d, upper values; n = 14) and low dairy fat intake (< 40 g/d, lower values; n = 27); means are different between both groups (unpaired t-Test): ‡ P < 0.1; # P < 0.05; ## P < 0.01.
² Means are different between maternal and fetal lipids in the respective group of dairy fat intake (paired t-Test): § P < 0.1 * P < 0.05; ** P < 0.01; *** P < 0.001.
