Kaplan-Meier analyses of progression from CIND to dementia. The index wave for respondents with CIND was defined as the wave with first indication of CIND. For respondents with gaps in cognitive assessment data, the last observed cognitive status was carried forward. Respondents who did not transition to dementia after the index wave were right-censored at the last wave with valid cognitive assessment data. Respondents were weighted using person-level weights (provided by the HRS) from 2004. Respondents without a positive weight in 2004 were excluded from the analysis.
