Swarm cases

receipt 7591: MPP2 in dopamine neurons, braak

power
full sample -0.29 (p 0.250, n 18), 95% CI -0.66 to +0.21. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.29 (p 0.250, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.30 (p 0.232, n 18). could be the mix.
skeptic
leave-one-out range -0.48 to -0.22, sign flips 0; without severely affected donors -0.29 (p 0.250, n 18). fragile.
cell type
strongest in oligodendrocytes: -0.75 (p 3.3e-4, n 18) vs -0.29 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for MPP2 in dopamine neurons.
