- From multivariate linear regression analyses adjusted for age, sex and baseline characteristics associated (p ≤ 0.15) with Gait Speed (GS) (measured + imputed) and Mini-Mental State Examination score: lives alone, education < 8 years, current smoker, depression, cerebrovascular disease, heart failure, history of hip fracture, malignancy previous 5 years, benzodiazepines, beta-blockers, analgesics, neuroleptics, number of prescribed medications, systolic blood pressure, vision impairment, hearing impairment and use of walking aid during gait speed test. In subgroup analyses with/without walking aids use of walking aids was omitted
- aParticipants who were unable to perform the GS test, and subsequently had a GS value imputed (n=287), had no reported walking aid and could therefore not be included in subgroup analyses of walking aid use
