↵* 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.
