Values for RA and Non-RA are the number (%) of episodes. aReference group patients without rheumatoid arthritis; badjusted for age, sex, comorbidities, admission type (emergency vs elective), patient type (public vs private), socioeconomic status and joint surgery type (hip, knee, ankle and shoulder joint arthroplasty/arthrodesis vs all other). MI myocardial infarction, CV cardiovascular, RA rheumatoid arthritis, O, odds ratio; CI confidence interval. Results in italics are statistically significant
