Distribution of the tear break-up time among participants with Keratoconjunctivitis Sicca-Only and those with Sjögren's Syndrome-Keratoconjunctivitis Sicca. Keratoconjunctivitis Sicca-Only cases have abnormal ocular staining score (OSS ≥ 3), but no focal lymphocytic sialadenitis or have focus scores <1 and have negative serology to anti-SS-A or B antibodies. Sjögren's Syndrome-Keratoconjunctivitis Sicca cases have OSS ≥ 3, focal lymphocytic sialadenitis with focus score >1 and/or positive anti-SS-A or B antibodies.
