The swarm's case

receipt 3977: SOX10 in oligodendrocytes, braak

power
full sample -0.10 (p 0.683, n 18), 95% CI -0.54 to +0.38. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.07 (p 0.781, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.03 (p 0.922, n 18). could be the mix.
skeptic
leave-one-out range -0.26 to -0.00, sign flips 0; without severely affected donors -0.10 (p 0.683, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for SOX10 in oligodendrocytes.

case closed: nothing better to follow up.
