Swarm cases

receipt 7628: C1R in dopamine neurons, braak

power
full sample -0.43 (p 0.072, n 18), 95% CI -0.75 to +0.04. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.39 (p 0.109, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.59 (p 0.010, n 18). not the mix.
skeptic
leave-one-out range -0.58 to -0.36, sign flips 0; without severely affected donors -0.43 (p 0.072, n 18). robust.
cell type
strongest in oligodendrocytes: -0.59 (p 0.0092, n 18) vs -0.43 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for C1R in dopamine neurons.

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

receipt 7627: C1R in astrocytes, braak

power
full sample -0.17 (p 0.498, n 18), 95% CI -0.59 to +0.32. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.17 (p 0.498, n 18). does not hold up.
composition
astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: -0.30 (p 0.221, n 18). could be the mix.
skeptic
leave-one-out range -0.32 to -0.06, sign flips 0; without severely affected donors -0.17 (p 0.498, n 18). fragile.
cell type
strongest in oligodendrocytes: -0.59 (p 0.0092, n 18) vs -0.17 in astrocytes. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for C1R in astrocytes.
