|---|---|---|---|---|
| Assessment of <7 cognitive domains | 9.882 | 0.610 (0.439–0.757) | 0.620 (0.451–0.764) | 0.652 |
| Assessment of ≥7 cognitive domains | 10.281 | 0.671 (0.510–0.799) | 0.647 (0.483–0.783) | 0.708 |
| All available studies | 10.217 | 0.647 (0.541–0.741) | 0.647 (0.522–0.755) | 0.683 |
