The swarm's case

receipt 12938: DDO in oligodendrocytes, braak

power
full sample -0.02 (p 0.949, n 18), 95% CI -0.48 to +0.45. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.05 (p 0.834, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.07 (p 0.794, n 18). could be the mix.
skeptic
leave-one-out range -0.16 to +0.13, sign flips 7; without severely affected donors -0.02 (p 0.949, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for DDO in oligodendrocytes.

case closed: nothing better to follow up.
