Both corrected (p ≤ 0.0015; in bold) and uncorrected (p ≤ 0.01) p values for multiple testing by trait are shown; for HbA1c, HC, FPI, HOMA IR, FPG and disposition index, inverse normalized values are shown; for TG, VLDL, BMI, WC, Matsuda index and ALT, log transformed values are shown.
Strong LD with r2 ranging from 0.87 to 0.98.
Strong LD with r2 = 0.90.
Strong LD with r2 ranging from 0.86 to 0.99.
Of the 34 significant (p ≤ 0.01) associations shown, 17 were found to replicate the same direction of association (i.e. same risk allele) as the one identified in the original GWAS or candidate gene studies (online suppl. table 1).
