  1. Fatty acid ratios are presented as the median in arbitrary units with the 25-75% interquartile range in parentheses. DD demonstrates a decrease in the vaccenic/stearic ratio in comparison to Controls and FML
  2. DD Dercum's disease, FML Familial multiple lipomatosis, MSL Multiple symmetric lipomatosis
  3. *p < 0.05 vs. Control; †p < 0.05 vs. FML; ‡ trended lower vs. Control (see text)
