Ordinary least squares (OLS) regression coefficients of ideology on gray matter volume
Each row represents a single analysis with the gray matter volume of a region as dependent variable, and the four ideology variables as independent variables. There is one exception: the original Kanai replication is based on four OLS regressions with single estimators. Dots represent the regression effect and bars the 90% CI. Black dots and bars indicate a significant relationship, gray ones denote an insignificant relationship.
