Fig. Linkage disequilibrium patterns between CDKN2B-AS1 (9p21.3) gene polymorphisms in POAG patients (АB) and controls (CD) Note: cells in figures on the left contain Lewontin’s standardized disequilibrium coefficient -values ( =1 corresponds to empty cell). Cell color reflects the degree of generic linkage between polymorphisms: red – tight linkage ( = 1; LOD > 2); pink – significant linkage ( < 1; LOD > 2); white — weak linkage ( < 1; LOD < 2). Haplotype blocks are marked by black lines. Cells in figures on the right contain Pearson correlation coefficient values (r2 )

Note: Results were obtained using the logistic regression model; OR — odds ratio, 95% CI — 95% confidence interval (lower and upper bound of 95% CI); p — significance level.
