Cognitive impairment
no changein humans1
Instrumental activities of daily living limitations have no effect on cognitive impairment in humans (p = .102).
“In contrast, baseline IADL limitations did not (p=.102).”

Cognitive impairment
upin humans1HR 1.08
Instrumental activities of daily living limitations raise the risk of cognitive impairment in humans (HR = 1.08, p < .001).
“increases in IADL limitations remained significantly related to a heightened risk of cognitive impairment (HR = 1.08, p<.001).”

Mortality
upin humans1HR 1.05
Instrumental activities of daily living limitations raise the risk of mortality in humans (HR = 1.05, p < .001).
“Overall, increased baseline IADL limitations were associated with an increased risk of death [hazards ratio (HR)=1.05, p<.001]”
