Statistical analysis
Independent sample T-test was used to compare sCD14 tear levels, and
CD14, TLR-4 and TLR-9 conjunctival expression between groups of patients
with VKC and healthy subjects. Paired sample T-test was used to compare
sCD14 tear levels, and CD14, TLR-4 and TLR-9 conjunctival expression
before and after topical corticosteroid treatment in group A. Clinical
parameters were correlated with CD14, TLR-4 and TLR-9 expression levels
by Sperman rho test. (SPSS 18, IBM, Chicago: SPSS Inc). P values
<0.05 were considered statistically significant.
