An area-proportional Venn diagram of the SICCA cohort (n = 1156) illustrates the partially overlapping relationships of three objective Sjören’s syndrome signs. 920 (80%) of the cohort had one or more of the following: positive serum anti-SS-A/B (n=455, 39%); LSG biopsy with FLS and FS >1 (n=491, 42%); ocular surface stain ≥3 (keratoconjunctivitis sicca - KCS) (n=833, 72%); 236 (20%) of the cohort had none of these.
