Swarm cases

receipt 16960: SPECC1 in dopamine neurons, braak

power
full sample +0.22 (p 0.374, n 18), 95% CI -0.27 to +0.62. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.21 (p 0.408, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.26 (p 0.298, n 18). could be the mix.
skeptic
leave-one-out range +0.10 to +0.35, sign flips 0; without severely affected donors +0.22 (p 0.374, n 18). fragile.
cell type
strongest in oligodendrocytes: -0.64 (p 0.0045, n 18) vs +0.22 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for SPECC1 in dopamine neurons.

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