  • Fixed effects and covariates fitted as shown in Table 2. Values significantly >0 based on a log-likelihood ratio test shown in bold.

  • a These two traits had the same definition but heritability estimates were slightly different due to different rules regarding treatment of missing values for individual C-BARQ responses.
