CXCL8 and Trichiasis: Pair-wise measures of linkage disequilibrium and regression modelling (figure 1, table 3) mapped the risk associations to the four contiguous SNPs bounded by AFM+1666 and IL8-251 (AFM+1666A/AFM+4530A/AFM+15790T/IL8-251A OR(95%CI) = 2.00 (1.30, 2,94) and 1.610 (0.99, 2.61) for scarring and trichiasis respectively).
