Adjusted for age and site
The effect estimates (ORs) for all continuous variables were expressed per standard deviation increment, except age, which was expressed per one-year increment. For continuous variables, odds ratios refer to increments of one standard deviation.
OR = odds ratio; COPD = chronic obstructive pulmonary disease; IADL = instrumental activities of daily living
