CRF
The main findings of this study were as follows: (i) to provide new equations with good predictive value for eCRF (74%-87%), specifically developed for older adults and using different scenarios of complexity (laboratory-based test and field-based test) and/or equipment requirements, and (ii) higher eCRF, even using its simplest equation, was associated with better performance on several cognitive dimensions (i.e., language, cognitive flexibility, fluency, attention, and working memory), similar to using objectively measured CRF.
