Swarm cases

receipt 9841: MAPK8IP1 in dopamine neurons, braak

power
full sample -0.41 (p 0.093, n 18), 95% CI -0.73 to +0.07. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.41 (p 0.093, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.49 (p 0.037, n 18). not the mix.
skeptic
leave-one-out range -0.62 to -0.36, sign flips 0; without severely affected donors -0.41 (p 0.093, n 18). robust.
cell type
strongest in oligodendrocytes: -0.59 (p 0.0092, n 18) vs -0.41 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for MAPK8IP1 in dopamine neurons.

receipt 9840: MAPK8IP1 in oligodendrocytes, braak

power
full sample -0.59 (p 0.0092, n 18), 95% CI -0.83 to -0.18. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.56 (p 0.015, n 18). holds up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.60 (p 0.0083, n 18). not the mix.
skeptic
leave-one-out range -0.72 to -0.54, sign flips 0; without severely affected donors -0.59 (p 0.0092, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for MAPK8IP1 in oligodendrocytes.

case closed: nothing better to follow up.
