CRP and synovial sarcoma: Contrary to our expectations, in this study, there were no significant differences in ocular surface parameters, including TBUT, Schirmer score, TCR and corneal/conjunctival staining score, and laboratory findings including ANA, RF, ESR, and CRP between the SS-DE groups according to satisfaction with 2016 revised criteria for SS (group 1 and 2), except for the presence of anti-SSA autoantibodies.
