All OR calculations are obtained computing the rare homozygous genotype vs the rest of genotypes comparing cases vs controls. OR1 is referred to the Progressive group in which the reference category is the RR subgroup. Corrected and uncorrected P-values are respectively referred to the presence/absence of Bonferroni correction. NS, not significant.
