Perception: weighted Cohen’s d effect sizes* for each test, rank ordered by size
| N >studies | N >participants | Mean >Cohen’s dw | SD dw(95% CI) | Min d | Max d | Nfs | %OL | Study references | |
|---|---|---|---|---|---|---|---|---|---|
| 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; SD dw, SD of weighted effect size; %OL, per cent overlap between Alzheimer’s disease and frontotemporal dementia groups; VOSP, Visual Object and Space Perception Battery; 95% CI, 95% CI for means. | |||||||||
