Linear regression analyses to assess effect of MAPT diplotype and GSK3B genotypes on total grey matter and intracranial volumea.

aGenotypes were tested separately in models including age and sex as a priori predictors. Values for all predictors in each model are given in Tables S1 and S2 in Information S1.bCoded as follows: MAPT, H1H1 = 0, H1H2 = 1, H2H2 = 2; rs3755557, AA = 0, AT = 1, TT = 2; rs334558, GG = 0, AG = 1, AA = 2.cMeta-analyses with a significant effect after correction for multiple comparisons are in bold.
