|Table 3: Prevalence of dementia (%) and its subtype by 10 years age group and by study site.|
|AD/VaD: the number of AD cases/the number of VaD cases. |
#Based on subsample analysis with MRI results.
N/A: sample size is too small to perform the calculation (AD + VaD cases < 5).
*Random sampling was used for screening. reported is not weighted. Prevalence, proportions of subtypes of dementia, and AD/VaD ratio used weighted frequencies to show those of the population at large.
