Swarm cases

receipt 13848: MAN2B2 in dopamine neurons, braak

power
full sample -0.16 (p 0.515, n 18), 95% CI -0.59 to +0.33. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.14 (p 0.579, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.21 (p 0.408, n 18). could be the mix.
skeptic
leave-one-out range -0.31 to -0.07, sign flips 0; without severely affected donors -0.16 (p 0.515, n 18). fragile.
cell type
strongest in oligodendrocytes: -0.63 (p 0.0055, n 18) vs -0.16 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for MAN2B2 in dopamine neurons.
