Swarm cases

receipt 0248: KAT8 in dopamine neurons, braak

power
full sample -0.15 (p 0.555, n 18), 95% CI -0.58 to +0.34. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.15 (p 0.555, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.16 (p 0.515, n 18). could be the mix.
skeptic
leave-one-out range -0.32 to -0.06, sign flips 0; without severely affected donors -0.15 (p 0.555, n 18). fragile.
cell type
strongest in microglia: +0.62 (p 0.0057, n 18) vs -0.15 in dopamine neurons. proposing microglia.
axis
no measure beats "tracks Braak Lewy-body stage" for KAT8 in dopamine neurons.

follow-up registered; not confirmed in substantia nigra, an independent cohort.
