Admissions for gastric (GU) and duodenal (DU) ulcers, and dyspepsia in all 12 London hospitals associated with a medical school. Gastric ulcer, duodenal ulcer, and “dyspepsia” (including indigestion, gastralgia, and gastritis) are presented as mean rates per 10 000 admission in each five year period. To further smooth out missing time periods and various lengths of data availability from individual hospitals, the data were plotted as the moving average of three consecutive time periods.
