receipt 5165: SMG1 in dopamine neurons, braak

power
full sample +0.31 (p 0.207, n 18), 95% CI -0.18 to +0.68. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.46 (p 0.054, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.51 (p 0.030, n 18). not the mix.
skeptic
leave-one-out range +0.21 to +0.41, sign flips 0; without severely affected donors +0.31 (p 0.207, n 18). fragile.
cell type
strongest in oligodendrocytes: +0.60 (p 0.0089, n 18) vs +0.31 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for SMG1 in dopamine neurons.
