No correlation was found between inflammation of the joints and age (p = 0.1), CRP level (p = 0.6), ESR (p = 0.6), FS (p = 0.4), leukocyte count (p = 0.7), RF titer (p = 0.8), gammaglobulin level (p = 0.6), severity of xerophthalmia (p = 0.6), and xerostomia (p = 0.2) as well as the presence of anti-SSA (p = 0.8), anti-SSB (p = 0.1), and anti-Ro52 (p = 0.2) antibodies. This evidence concerns the gene SSB and Keratoconjunctivitis sicca.
