Prevalence of Independence at Baseline and Visit 2 in All Participants and Survivors
| Number (%) (n for reduced sample) | Difference (95% CI) | ||
|---|---|---|---|
| Valid Physical or Valid*/All† Cognitive Data at Baseline (n = 1442/n = 1496) | Valid Physical or Valid/All Cognitive Data at Visit 2 (n = 384/n = 391) | ||
| Overall independent (valid)* | 771 (67.3%) (n = 1146) | 195 (59.1%) (n = 330)‡ | −8.2% (−14.1; −2.2) |
| Overall independent (all)† | 866 (66.4%) (n = 1304) | 213 (59.7%) (n = 357) | −6.7% (−12.4; −1.0) |
| Physically independent | 1151 (83.8%) (n = 1373) | 264 (74.0%) (n = 357) | −9.9% (−14.8; −4.9) |
| Cognitively independent (valid) | 889 (79.7%) (n = 1115) | 246 (79.6%) (n = 309) | −0.1% (−5.2; 5.0) |
| Cognitively Independent (all) | 1036 (74.5%) (n = 1391) | 273 (74.8%) (n = 365) | 0.3% (−4.7; 5.3) |
Note: MMSE = Mini-Mental State Examination.
*Valid refers to using only valid MMSE exams.
†All refers to using all MMSE exams.
‡These n’s do not match those in Table 2. due to some participants having valid data at visit 2 but not at visit 1.
