Figure 1From: Association between IL-18gene polymorphisms and biopsy-proven giant cell arteritisCombined effects of the risk alleles of ( IL18 -607 and -1297) and TLR4 (Asp299Gly) on susceptibility to GCA. Linear regression analysis showed an additive effect of the risk alleles of the IL18 and TLR4 on GCA susceptibility. The ORs with 95% CI are shown as a function of number of risk alleles of GCA.Back to article page
