The swarm's case

receipt 0891: ZNF462 in oligodendrocytes, 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
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.16 (p 0.521, n 18). could be the mix.
skeptic
leave-one-out range +0.03 to +0.27, 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 ZNF462 in oligodendrocytes.

case closed: nothing better to follow up.
