The swarm's case

receipt 7282: ZNF395 in dopamine neurons, braak

power
full sample +0.20 (p 0.424, n 18), 95% CI -0.29 to +0.61. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.20 (p 0.429, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.13 (p 0.615, n 18). could be the mix.
skeptic
leave-one-out range +0.07 to +0.33, sign flips 0; without severely affected donors +0.20 (p 0.424, n 18). fragile.
cell type
strongest in oligodendrocytes: -0.61 (p 0.0067, n 18) vs +0.20 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for ZNF395 in dopamine neurons.
