Figure 1. The genotype polymorphism of IL1βrs1143634 and IL1βrs16944. A: The frequencies of *C/*T genotype of IL1βrs1143634 in non-Sjogren dry eye patients was increased compared with the control subjects (10.4% versus 3.9%, p=0.043, OR=3.337). B: No significant differences were shown in the IL1βrs16944 polymorphism.
