Swarm cases

receipt 4665: COQ8A in dopamine neurons, braak

power
full sample -0.45 (p 0.062, n 18), 95% CI -0.76 to +0.02. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.42 (p 0.080, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.47 (p 0.047, n 18). not the mix.
skeptic
leave-one-out range -0.58 to -0.38, sign flips 0; without severely affected donors -0.45 (p 0.062, n 18). robust.
cell type
strongest in oligodendrocytes: -0.65 (p 0.0037, n 18) vs -0.45 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for COQ8A in dopamine neurons.
