approached significancep < 0.001
When both cognitive and functional decline were included in the outcome models, both terms were significant or approached significance for overall caregiver time ( p < 0.001 for cognitive decline and p = 0.062 for functional decline), supervision time ( p = 0.010 and 0.003, respectively), and total societal cost ( p < 0.001 and p = 0.045, respectively).
