The swarm's case

receipt 10014: LRP4 in oligodendrocytes, braak

power
full sample -0.26 (p 0.302, n 18), 95% CI -0.65 to +0.24. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.15 (p 0.544, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.10 (p 0.690, n 18). could be the mix.
skeptic
leave-one-out range -0.45 to -0.19, sign flips 0; without severely affected donors -0.26 (p 0.302, n 18). fragile.
cell type
strongest in astrocytes: +0.60 (p 0.0089, n 18) vs -0.26 in oligodendrocytes. proposing astrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for LRP4 in oligodendrocytes.
