Serum salicylate concentrations measured after ≥12-hour fast in patients who presented with a recurrent ulcer after surgery for peptic ulcer. In each case the data are presented separately for those who gave a positive history of aspirin use (Pos, 1–4 g/day; ○) and for those who denied using aspirin (Deny; ●).
