fERG threshold and slope in patients carriers of the ARMS2 (rs10490924) polymorphism. Box-whiskers plots of fERG threshold and slope values at baseline (V0) and after three (V3), six (V6), nine (V9) and twelve (V12) months of Saffron treatment, in wild type (n = 20), heterozygous (n = 8) and homozygous (n = 5) patients, for the ARMS2 (rs10490924) polymorphism. In each diagram the symbol is the mean, the box indicates the median and interquartile range and bars indicate the 95 percentiles.
