  1. Comparison of the risk allele frequencies (RAFs) between Central and Southern European controls, and linear regression of RAFs to the North/South score (N/S score) of population differentiation (from Table 1). NS, not significant. aAnalysis performed only in women because the locus is in the X chromosome.
