"These results translate into an absolute rate increase with aspirin above placebo (the incidence of cases of major GI bleeding attributable to low-dose aspirin) of 0.12% per year (95% CI: 0.07–0.19% per year).[20] Based on this value, 833 patients (95% CI: 526–1429 patients) would need to be treated with low-dose aspirin instead of placebo to cause one major GI bleeding episode during a 1-year period (i.e. the NNH is 833)"
Anyone else care to share quantitative risk numbers?
