The swarm's case

receipt 7925: TSPOAP1 in astrocytes, braak

power
full sample +0.13 (p 0.615, n 18), 95% CI -0.36 to +0.56. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.14 (p 0.585, n 18). does not hold up.
composition
astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: +0.25 (p 0.315, n 18). could be the mix.
skeptic
leave-one-out range +0.02 to +0.26, sign flips 0; without severely affected donors +0.13 (p 0.615, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for TSPOAP1 in astrocytes.

case closed: nothing better to follow up.
