  • CI, confidence interval; NF, neurofeedback.

  • a Data are presented as means (SD).

  • b The growth model estimates a coefficient representing a change in the slope between the intervention conditions and the control condition over the 3 time points.

  • c Quadratic model also estimated (see text); results of the linear model shown.

  • d Approximate effect size estimate for linear growth coefficient.
