Concordant enriched pathways among GWA datasets of the GAIN and the WTCCC by different pathway-based methods.

ASM: Gene set of allele-specific methylation; GSEA: Gene Set Enrichment Analysis; SUMST: sum-statistic; SUMSQ: sum-square-statistic.#: The p-value after correction by the Benjamini and Hochberg (BH) multiple comparison procedure.a: Empirical p-values of non-weighting method is less than weighting;b: Empirical p-values of weighting method is less than non-weighting;c: Empirical p-values of non-weighting and weighting are equivalent.
