Note. Estimated marginal means are estimated from a mixed-model with group number as a random effect (to account for clustering effects) and intervention condition and time as fixed effects, covarying for verbal fluency to account for group difference in verbal fluency at baseline. Note that verbal fluency was not covaried when analysing change in process measures.
