Brain volume composite score
upin humans1
Brain volume composite score is associated with sleep score in humans (r = 0.18).
“Correlation analyses revealed significant associations between brain volume composite scores and both sleep ( r = 0.18) and cognition ( r = 0.15) scores”

The highest sleep-score group had a hazard ratio of 0.47, a measure comparing risk over time, against the lowest group during 12.9 years’ average follow-up.The highest sleep-score group had a hazard ratio of 0.47, a measure comparing risk over time, against the lowest group during 12.9 years’ average follow-up.
Higher sleep-linked protein scores were associated with a lower depression rate during follow-up (hazard ratio 0.660); the abstract did not specify the comparison group.Higher sleep-linked protein scores were associated with a lower depression rate during follow-up (hazard ratio 0.660); the abstract did not specify the comparison group.
