1From Brown et al. [19], originally referenced in Brown 1999 [20].
2 C a l c u l a t e d based on utility decrement associated with a major stroke, from meta-analysis by Tengs and Lin 2003 [21].
3 F r o m Tsevat et al. [22].
4 B a s e d on 3-month utility for a severe gastrointestinal hemorrhage requiring medical intervention, from Maetzel et al. 2001 [23]. Patients were assumed to return to full health for the duration of the cycle.
95% CI: 95% confidence interval; BCVA: best-corrected visual acuity; CVA: cerebrovascular accident; MI: myocardial infarction; NOH: nonocular hemorrhage.
