Table 2.
Comparison of the 5-task index of CogEvo between the COPD group and the healthy older group (mean ± SD).
| Cognitive function items | COPD (n=28) | Healthy (n=30) | p |
|---|---|---|---|
| Spatial cognition | 102.2±31.4 | 101.5±15.8 | 0.917 |
| Orientation | 122.2±25.8 | 105.7±17.4 | 0.006** |
| Working memory | 84.5±18.0 | 102.6±16.9 | <0.001** |
| Executive function | 86.8±22.8 | 101.4±17.3 | 0.008** |
| Attention | 96.5±14.4 | 110.4±17.4 | 0.002* |
The results of the analysis of variance confirmed an interaction (p<0.001) and a main effect between two groups (p<0.001). The p in the table indicate comparisons between two groups with the Tukey-Kramer method as a subtest; *p<0.05; **p<0.01.
