Fixed effects estimates, standard error (SE), lower and upper 95% confidence interval, t-value and p-value. Sqrt corresponds to square root. Intercept corresponds to the intercepts (trial 1) of the reference group (balance group). Intercept is tested against zero. Group Control and Group Power correspond to the difference between Intercept and the intercept of the control and power group. Trial corresponds to the slope of the reference group (i.e. the balance group). Trial: Group Control and Trial: Group Power correspond to the difference between the slope of the balance group (Trial) and the slope of the control and power group
One star indicates a significant difference with p < 0.05. Three stars indicate a significant difference with p < 0.001
