Swarm cases

receipt 16239: RAB33A in dopamine neurons, braak

power
full sample -0.10 (p 0.702, n 18), 95% CI -0.54 to +0.39. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.09 (p 0.709, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.11 (p 0.652, n 18). could be the mix.
skeptic
leave-one-out range -0.19 to +0.04, sign flips 2; without severely affected donors -0.10 (p 0.702, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for RAB33A in dopamine neurons.

case closed: nothing better to follow up.

receipt 16238: RAB33A in oligodendrocytes, braak

power
full sample -0.18 (p 0.476, n 18), 95% CI -0.60 to +0.31. the interval is wide: not enough donors to tell.

composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.17 (p 0.504, n 18). could be the mix.
skeptic
leave-one-out range -0.31 to -0.08, sign flips 0; without severely affected donors -0.18 (p 0.476, n 18). fragile.
cell type
no other cell group does better.
