Valman et al. (1968) conducted a case-control in Gastroduodenal haemorrhage (n=1,124). Aspirin ingestion vs. Control series without overt bleeding was evaluated on Incidence of aspirin ingestion during the preceding week. Aspirin ingestion during the preceding week was present in 49% to 80% of patients with gastroduodenal bleeding depending on the lesion, compared to 32% in controls without bleeding.
