Wall Penetration Count

upin humans1

1 study
  1. Amyloid spatial extent is associated with Wall Penetration Count in humans (β=0.03, p=0.03, R2=0.18).

Speed

upin humans1

1 study
  1. Amyloid spatial extent is associated with Speed in humans (β=0.28, p=0.03, R2=0.19).

    “higher EXT% was significantly associated with greater speed (β=0.28, p =0.03, R2=0.19) and Wall Penetration Count (β=0.03, p =0.03, R2=0.18) in the NC condition”

Speed variability

upin humans1

1 study
  1. Amyloid spatial extent is associated with speed variability in humans (β=1.69, p=0.01, R2=0.19).

    “higher speed variability (β=1.69, p =0.01, R2=0.19) than the EXT− group”

Pen Off Page Time

upin humans1

1 study
  1. Amyloid spatial extent is associated with Pen Off Page Time in humans (β=4.70, p=0.03, R2=0.13).

    “In the CH condition, the EXT++ group exhibited significantly longer Pen Off Page Time (β=4.70, p =0.03, R2=0.13) and higher speed variability (β=1.69, p =0.01, R2=0.19) than the EXT− group.”
