Swarm cases

receipt 4141: HGS in dopamine neurons, braak

power
full sample -0.28 (p 0.254, 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 0.243, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.28 (p 0.261, n 18). could be the mix.
skeptic
leave-one-out range -0.47 to -0.18, sign flips 0; without severely affected donors -0.28 (p 0.254, n 18). fragile.
cell type
strongest in oligodendrocytes: -0.73 (p 6.2e-4, n 18) vs -0.28 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for HGS in dopamine neurons.

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