↵* p < 0.05 in the Rao-Scott chi-square test comparing the proportion of persons in the income groups. For persons with low, medium, and high incomes, n = 22 (6.3%), 26 (3.6%), and 2 (0.7%), respectively, did not report on the influence of RA on their working life. Bold face indicates statistically significant influence on the outcome. RA: rheumatoid arthritis.
