Timeline for FFQ, PFD and biomarker (serum phospholipid fatty acids). 1FFQ asks for the last year’s diet, filled in 2–8 days before surgery. 2FFQ asks for the last month’s diet. The PFD is filled in for seven consecutive days shortly after surgery (10 +/− 2 days after surgery), at six and twelve months postsurgery. The blood samples (biomarker) are drawn 2–8 days presurgery, at six and twelve months postsurgery
