The swarm's case

receipt 6196: NDE1 in oligodendrocytes, braak

power
full sample -0.44 (p 0.067, n 18), 95% CI -0.75 to +0.03. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.43 (p 0.075, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.46 (p 0.052, n 18). could be the mix.
skeptic
leave-one-out range -0.55 to -0.37, sign flips 0; without severely affected donors -0.44 (p 0.067, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for NDE1 in oligodendrocytes.

case closed: nothing better to follow up.
