^*BADL = basic activities of daily living

^†IADL = instrumental activities of daily living

^‡OR = odds ratio; compares the odds of disability among people in each impairment category to the odds of disability among people with neither impairment

^§CI = confidence interval

^¶Weighted prevalence of disability
