Swarm cases

receipt 12360: APBB1 in dopamine neurons, braak

power
full sample -0.12 (p 0.640, n 18), 95% CI -0.55 to +0.37. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.19 (p 0.444, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.18 (p 0.471, n 18). could be the mix.
skeptic
leave-one-out range -0.19 to +0.02, sign flips 2; without severely affected donors -0.12 (p 0.640, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for APBB1 in dopamine neurons.

case closed: nothing better to follow up.

receipt 12359: APBB1 in oligodendrocytes, braak

power
full sample -0.32 (p 0.198, n 18), 95% CI -0.68 to +0.17. the interval is wide: not enough donors to tell.

adjusted for sex: -0.38 (p 0.118, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.36 (p 0.142, n 18). could be the mix.
skeptic
leave-one-out range -0.45 to -0.22, sign flips 0; without severely affected donors -0.32 (p 0.198, n 18). fragile.
cell type
no other cell group does better.
