  • * Evaluable subjects were 22 (placebo) and 23 (EPA-FFA) for polyp number; and 19 (placebo) and 21 (EPA-FFA) for polyp diameter.

  • A negative difference between treatment groups indicates a decrease in the EPA-FFA group compared with the placebo group.

  • A negative value implies an increased global polyp burden. A positive value implies a decreased global polyp burden. Evaluable subjects were 25 in each of the placebo and EPA-FFA groups.

  • BL, baseline, EPA-FFA, eicosapentaenoic acid as the free fatty acid.
