^aThe number (%) of patients with abnormal nailfold videocapillaroscopy findings is shown separately for each patient group. An abnormal finding was defined as a score greater than 0 (range, 0–3)
^bFisher exact test
^cCapillaroscopy density was not available for 1 participant in the control group; that participant was not included in the denominator for the primary outcome
