Myocardial infarction in relation to primary Sjögren's syndrome duration and age. (a) Incidence rate and hazard ratio of myocardial infarction (MI) in primary Sjögren's syndrome, stratified by years since Sjögren's syndrome diagnosis. Seventeen patients with Sjögren's syndrome did not have available records on Ro/SSA and La/SSB antibodies and are not included in subgroup analyses. (b) Age‐specific incidence rate and hazard ratio of MI with 95% confidence intervals (CI) in prevalent Sjögren's syndrome, and in population‐based comparators. ¹Primary Sjögren's syndrome patients, ²General population comparators. CI, confidence interval; NA, not applicable.
