receipt 14027: ARAP2 in dopamine neurons, braak

power: full sample -0.06 (p 0.807, n 18), 95% CI -0.51 to +0.42. the interval is wide: not enough donors to tell.
confounder: adjusted for sex: -0.08 (p 0.748, n 18). does not hold up.
composition: dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.03 (p 0.922, n 18). could be the mix.
skeptic: leave-one-out range -0.21 to +0.06, sign flips 4; without severely affected donors -0.06 (p 0.807, n 18). fragile.
cell type: no other cell group does better.
axis: no measure beats "tracks Braak Lewy-body stage" for ARAP2 in dopamine neurons.

case closed: nothing better to follow up.

receipt 14026: ARAP2 in oligodendrocytes, braak

power: full sample +0.11 (p 0.664, n 18), 95% CI -0.38 to +0.55. the interval is wide: not enough donors to tell.
confounder: adjusted for sex: +0.16 (p 0.538, n 18). does not hold up.
composition: oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.26 (p 0.306, n 18). could be the mix.
skeptic: leave-one-out range -0.00 to +0.17, sign flips 3; without severely affected donors +0.11 (p 0.664, n 18). fragile.
cell type: no other cell group does better.
axis: no measure beats "tracks Braak Lewy-body stage" for ARAP2 in oligodendrocytes.

case closed: nothing better to follow up.
