Reported means and standard deviations are based on raw, untransformed scores. Between group effect sizes at each timepoint were calculated using the difference between model estimated means (AE-HE) divided by the pooled, weighted standard deviation of baseline raw scores of the dependent variable (Cohen, 1988; Feingold, 2013).
