Summary statistics for the discovery meta-analysis epigenome-wide association study (EWAS) of total nicotine equivalents (TNE) in the Multiethnic Cohort Study (meta-analysis of five race- and ethnicity-specific EWAS: African American, European American, Japanese American, Latino, Native Hawaiian). Results from each race- and ethnicity-specific EWAS are included as additional columns. Estimates from the models represent the change in methylation β-value per one log-unit increase in TNE.
Column descriptions:
probe_id: CpG probe IDchr: Chromosome containing the CpG (Build 37)mapinfo: Chromosomal coordinates of the CpG (Build 37)strand: The Forward (F) or Reverse (R) designation of the Design Strandgene: Target gene names, from the UCSC databasegene_group: Gene region feature category describing the CpG position, from UCSC. Features are listed in the same order as the target gene transcriptsmeta_est: Parameter estimate for the race and ethnicity meta-analyzed association between TNE and DNA methylationmeta_se: Standard error of the parameter estimate for the race and ethnicity meta-analyzed association between TNE and DNA methylationmeta_p: P-value for the race and ethnicity meta-analyzed association between TNE and DNA methylationmeta_direction: The direction (positive or negative) of the race- and ethnicity-specific parameter estimates for African Americans, European Americans, Japanese Americans, Latinos, and Native Hawaiians, respectivelymeta_het_i_sq: The heterogeneity I2 statistic for the race and ethnicity meta-analysis across the five racial and ethnic groupsmeta_het_p: The heterogeneity p-value for the race and ethnicity meta-analysis across the five racial and ethnic groupsaa_est: Parameter estimate for the African American-specific association between TNE and DNA methylationaa_se: Standard error of the parameter estimate for the African American-specific association between TNE and DNA methylationaa_p: P-value for the African American-specific association between TNE and DNA methylationea_est: Parameter estimate for the European American-specific association between TNE and DNA methylationea_se: Standard error of the parameter estimate for the European American-specific association between TNE and DNA methylationea_p: P-value for the European American-specific association between TNE and DNA methylationja_est: Parameter estimate for the Japanese American-specific association between TNE and DNA methylationja_se: Standard error of the parameter estimate for the Japanese American-specific association between TNE and DNA methylationja_p: P-value for the Japanese American-specific association between TNE and DNA methylationl_est: Parameter estimate for the Latino-specific association between TNE and DNA methylationl_se: Standard error of the parameter estimate for the Latino-specific association between TNE and DNA methylationl_p: P-value for the Latino-specific association between TNE and DNA methylationnh_est: Parameter estimate for the Native Hawaiian-specific association between TNE and DNA methylationnh_se: Standard error of the parameter estimate for the Native Hawaiian-specific association between TNE and DNA methylationnh_p: P-value for the Native Hawaiian-specific association between TNE and DNA methylation
