Symptoms and DED related examinations in the patients with pSS compared to non-SS-related MGD. Values equal the mean ± SE. DED, dry eye disease; MGD, meibomian gland dysfunction; pSS, primary Sjögren syndrome; OSDI, Ocular Surface Disease Index; CFS, corneal fluorescein staining.
a, b
Significantly (ap < 0.05, bp ≤ 0.01) greater than in the controls.
