The swarm's case

receipt 2736: CNTNAP4 in oligodendrocytes, braak

power
full sample +0.08 (p 0.754, n 18), 95% CI -0.40 to +0.53. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.05 (p 0.854, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.16 (p 0.526, n 18). could be the mix.
skeptic
leave-one-out range -0.02 to +0.24, sign flips 3; without severely affected donors +0.08 (p 0.754, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for CNTNAP4 in oligodendrocytes.

case closed: nothing better to follow up.
