| Activities of Daily Living total score2 (SD) | 392 | 22.32 (2.6) | 22.83 (2.1) | t (353.25) = 2.15 | .032* | d = .122 |
Notes.
1
Analytic sample sizes vary due to missing data. When appropriate, the unequal variance (Welch) t-test was used.
2
Higher scores on the Activities of Daily Living total score indicate more functional independence.

Significant at p=.05;
***
Significant at p = .001. P-values are unadjusted. Effect sizes were calculated with odds ratios (OR) with unadjusted 95% confidence intervals (CI) and Cohen’s d.
