*with Bonferroni correction (correction factor = 18)

The distribution of KIR haplotypes among psoriasis patients and controls obtained with NullHap based on genotypes reported by Luszczek et al. [16]. Only haplotypes with frequency > 5% in either group are shown. Odds ratio (OR) calculated according to Haldane [22], P value calculated by Fisher exact test. NS -not significant.
