receipt 10432: SLC25A20 in dopamine neurons, braak

power
full sample -0.18 (p 0.465, n 18), 95% CI -0.60 to +0.31. 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: -0.18 (p 0.471, n 18). could be the mix.
skeptic
leave-one-out range -0.28 to -0.07, sign flips 0; without severely affected donors -0.18 (p 0.465, n 18). fragile.
cell type
strongest in oligodendrocytes: -0.61 (p 0.0072, n 18) vs -0.18 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for SLC25A20 in dopamine neurons.
