GenoPheno was used to calculate the P-value for lack of correlation between the predicted phenotype (based on all 4 known LP-associated alleles) and the observed phenotype at locations where the ethnic groups were similar, and so expected to have a good genotype-phenotype correlation. Unlike figures 5 and 6, interpolation was not used here, but rather observed points analyses.
