receipt 3280: PI4K2A in dopamine neurons, braak

power
full sample +0.10 (p 0.702, n 18), 95% CI -0.39 to +0.54. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.05 (p 0.847, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.02 (p 0.928, n 18). could be the mix.
skeptic
leave-one-out range -0.01 to +0.21, sign flips 1; without severely affected donors +0.10 (p 0.702, n 18). fragile.
cell type
strongest in oligodendrocytes: -0.67 (p 0.0025, n 18) vs +0.10 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for PI4K2A in dopamine neurons.
