Swarm cases

receipt 10101: HDAC5 in dopamine neurons, braak

power
full sample -0.39 (p 0.114, n 18), 95% CI -0.72 to +0.10. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.37 (p 0.127, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.41 (p 0.095, n 18). could be the mix.
skeptic
leave-one-out range -0.50 to -0.30, sign flips 0; without severely affected donors -0.39 (p 0.114, n 18). fragile.
cell type
strongest in oligodendrocytes: -0.77 (p 1.8e-4, n 18) vs -0.39 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for HDAC5 in dopamine neurons.
