Abbreviations: PwCI, person with mild cognitive impairment or dementia; ACP, advance care planning; AD, advance directive; CAPACITY, caregiver perceptions about communication with clinical team members; TICS-M, an abbreviated version of the telephone interview cognitive status.
Note. Both odds ratios and marginal effects (the estimated % change in the dependent variable, for every one unit change in the predictor), were estimated from a logistic regression model in which PwCI-reported completion of ADs was the dependent variable.
