receipt 12593: PC in dopamine neurons, braak

power
full sample -0.27 (p 0.281, n 18), 95% CI -0.65 to +0.23. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.29 (p 0.239, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.34 (p 0.173, n 18). could be the mix.
skeptic
leave-one-out range -0.40 to -0.18, sign flips 0; without severely affected donors -0.27 (p 0.281, n 18). fragile.
cell type
strongest in oligodendrocytes: -0.74 (p 4.4e-4, n 18) vs -0.27 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for PC in dopamine neurons.
