ACE, Addenbrooke's Cognitive Examination; Max d, maximum effect size; Mean dw, mean weighted effect size; Min d, minimum effect size; N, number of studies contributing to the effect size; Nfs, fail safe N; %OL, per cent overlap between the Alzheimer's disease and frontotemporal dementia groups; SD dw, SD of weighted effect size; WAIS, Wechsler Adult Intelligence Scale (all editions); 95% CI, 95% CI for means.
*Effect sizes weighted by the inverse variance.
