The swarm's case

receipt 7229: ZNF112 in oligodendrocytes, braak

power
full sample +0.18 (p 0.487, n 18), 95% CI -0.32 to +0.59. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.25 (p 0.315, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.35 (p 0.156, n 18). could be the mix.
skeptic
leave-one-out range +0.07 to +0.32, sign flips 0; without severely affected donors +0.18 (p 0.487, n 18). fragile.
cell type
strongest in OPCs: -0.63 (p 0.0049, n 18) vs +0.18 in oligodendrocytes. proposing OPCs.
axis
no measure beats "tracks Braak Lewy-body stage" for ZNF112 in oligodendrocytes.
