receipt 14158: QSOX1 in dopamine neurons, braak

power
full sample -0.12 (p 0.633, n 18), 95% CI -0.56 to +0.37. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.06 (p 0.800, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.28 (p 0.265, n 18). could be the mix.
skeptic
leave-one-out range -0.25 to -0.01, sign flips 0; without severely affected donors -0.12 (p 0.633, n 18). fragile.
cell type
strongest in oligodendrocytes: -0.67 (p 0.0024, n 18) vs -0.12 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for QSOX1 in dopamine neurons.
