Values are the mean ± SD unless otherwise indicated. RA = rheumatoid arthritis; HAQ DI = Health Assessment Questionnaire disability index; DAS28‐ESR = Disease Activity Score in 28 joints using the erythrocyte sedimentation rate; CCP = cyclic citrullinated peptide; RF = rheumatoid factor; DMARDs = disease‐modifying antirheumatic drugs.
For patients with lymphoma, history of Sjögren's syndrome was specifically queried at the time of lymphoma event. Collection of Sjögren's syndrome history was not systematically performed for patients in the matched control group.
