SNP pairs, triplets and quartets that were identified by the p-value combination method in GWAS were verified in CMAS. Truncated product p-value statistics were calculated by combing single p values from the previous single-locus ULR-NOMINAL analysis or ULR-ORDINAL analysis in CMAS. The exact p values (in −log10 scale) for the combined and independent samples are shown.
