Subnormal Cytokine Profile in the Tear Fluid of Keratoconus Patients
Figure 2
Decrease in IL-4 measured by standard ELISA.
Samples shown in Table S2 were pooled into 13 control and 10 keratoconus samples (Methods). Each ELISA value is an average of two measurements. The decrease in IL-4 in the keratoconus pool (7.6±5 pg/ml), compared to controls (14.2±8.6 pg/ml) was statistically significant (p≤0.05, Mann-Whitney test). The horizontal bar indicates the mean value for each group.
