The swarm's case

receipt 5849: SOX13 in oligodendrocytes, braak

power
full sample -0.03 (p 0.894, n 18), 95% CI -0.49 to +0.44. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.10 (p 0.702, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.23 (p 0.365, n 18). could be the mix.
skeptic
leave-one-out range -0.13 to +0.10, sign flips 5; without severely affected donors -0.03 (p 0.894, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for SOX13 in oligodendrocytes.

case closed: nothing better to follow up.
