Values represent mean score (95% confidence interval) of the indicated metric adjusted for: Age, sex, education level, race, Charlson co-morbidity index, smoking status, radiographic knee pain, hip pain and cohort type (incidence, progression), and baseline scoring (Short Form 12, Physical Activity Scale for the Elderly) where available. Models stratified by age adjust for the similar co-variates other than age. Cohort included in the modeling includes all eligible subjects with follow-up data on outcomes of Short Form 12, Physical Activity Scale for the Elderly and Late-Life Function and Disability Instrument (n=1,729)
