AMs users were those who received AMs for at least 6\u00a0months after entering the cohort. AMs users and non-users were matched for age, sex, ethnicity, and baseline SDI using stratified random sampling. Two comparisons were carried out: patients with and without new damage, and AM users versus non-users.

During a median follow-up of 48.5 (IQR 19.3, 69.0) months, 472 (55.5%) developed damage. The most affected domains were skin (18.4%), renal (14.6%), neuropsychiatric (10.8%), musculoskeletal (6.9%), and cardiovascular (4.5%). AMs use was associated with a lower proportion of patients accruing damage at follow-up (170 [40.6%] vs 208 [48.3%];\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      = .028).
