The swarm's case

receipt 8278: SLC22A3 in oligodendrocytes, braak

power
full sample -0.15 (p 0.555, n 18), 95% CI -0.58 to +0.34. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.13 (p 0.597, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.16 (p 0.538, n 18). could be the mix.
skeptic
leave-one-out range -0.25 to -0.03, sign flips 0; without severely affected donors -0.15 (p 0.555, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for SLC22A3 in oligodendrocytes.

case closed: nothing better to follow up.
