  1. a“Unclear = dementia” indicates that subjects who were classified as “unclear” during the manual chart review are classified in the “dementia” group and the rate of undiagnosed dementia is calculated using this formula: (# of dementias + # of unclears) / (# of dementias + # of unclears + # of non-dementias). Conversely, “Unclear = non-dementia” indicates that subjects who were classified as “unclear” during the manual chart review are classified in the “non-dementia” group and the rate of undiagnosed dementia is calculated using this formula: (# of non-dementias + # of unclears) / (# of dementias + # of unclears + # of non-dementias)
