Incident severe reported mobility disability	773	159	20.6	775	203	26.2	0.78	0.64–0.96	0.02

Note: For BADL outcomes, 55, 69 and 2 participants had reported the outcome of dependency, disability and severe disability, respectively, at baseline. For IADL disability, 58 participants reported having difficulty or inability to perform at least one task at baseline making an analytic sample of 1577 participants. For mobility disability, 479 (29% of the cohort) participants reporting having “a lot of difficulty” or “unable” to perform one of the eight mobility tasks on the PAT-D.
