a
Data are presented as medians (minimum-maximum), means ± standard deviation, or %. Few participants had missing data on hypertension (n = 10), smoking (n = 2), alcohol use (n = 6), and physical activity (n = 10).
b
Quartiles of oleic acid presented as percent of total fatty acids.
c
Plasma phospholipid fatty acids expressed as percentage of total plasma phospholipids (SFA: saturated fatty acids). Palmitoleic acid, 16:1.
d
