From: Falls in advanced old age: recalled falls and prospective follow-up of over-90-year-olds in the Cambridge City over-75s Cohort study

Study participant characteristics Prevalence: How common is falling or repeated falling >90 years? Incidence: How frequently do >90-year-olds fall?
  n Recalled ≥ 1 fall in past year n (%) Relative Risk – unadjusted RR (95% C.I.) Recalled ≥ 2 falls in past year n (%) Relative Risk – unadjusted RR (95% C.I.)
