  1. Notes:± The inclusion of SES did not improve the fit of the model and it was therefore not included.
  2. *CI = 95% confidence interval; with level 2 variation (Between individuals) and with level 1 variation (within individuals or repeated measures)
  3. † = significant at p < 0.05;¥ Reference category = boys; ** reference category = control.
