receipt 7623: ADA in dopamine neurons, braak

power
full sample -0.07 (p 0.794, n 18), 95% CI -0.52 to +0.41. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.05 (p 0.840, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.09 (p 0.728, n 18). could be the mix.
skeptic
leave-one-out range -0.18 to +0.05, sign flips 3; without severely affected donors -0.07 (p 0.794, n 18). fragile.
cell type
strongest in oligodendrocytes: -0.63 (p 0.0055, n 18) vs -0.07 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for ADA in dopamine neurons.
