↵^a The OR is the exponential form of the β coefficient, which represents the multiplier factor for the odds of being employed when the covariate increases by 1; the reference for each comorbidity is the absence of the condition.
↵^* P < 0.05.
↵^** P < 0.001.
COPD: chronic obstructive pulmonary disease; RA: rheumatoid arthritis.
