First row: standardized path estimates for cognitive assessments in CALM & NKI-Rockland samples. Second row: raw path estimates with standard errors (parentheses). Third row: 95 % confidence intervals [brackets]. NA = not applicable. Note that age groups were determined according to the median split (CALM: 8.91 years, NKI: 11.38 years).
