Cerebral infarction in relation to primary Sjögren's syndrome duration and age. (a) Incidence rate and hazard ratio of cerebral infarction in primary Sjögren's syndrome, stratified by years since Sjögren's syndrome diagnosis. Seventeen patients with pSS 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 cerebral infarction 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.
