The swarm's case

receipt 9236: INF2 in oligodendrocytes, braak

power
full sample -0.48 (p 0.044, n 18), 95% CI -0.77 to -0.02. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.53 (p 0.025, n 18). holds up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.53 (p 0.025, n 18). not the mix.
skeptic
leave-one-out range -0.57 to -0.41, sign flips 0; without severely affected donors -0.48 (p 0.044, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for INF2 in oligodendrocytes.

case closed: nothing better to follow up.
