The swarm's case

receipt 7654: LUZP2 in oligodendrocytes, braak

power
full sample -0.03 (p 0.915, n 18), 95% CI -0.49 to +0.45. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.07 (p 0.787, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.00 (p 0.997, n 18). could be the mix.
skeptic
leave-one-out range -0.18 to +0.11, sign flips 7; without severely affected donors -0.03 (p 0.915, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for LUZP2 in oligodendrocytes.

case closed: nothing better to follow up.
