Swarm cases

receipt 14747: ADAM8 in dopamine neurons, braak

power
full sample -0.23 (p 0.355, n 18), 95% CI -0.63 to +0.26. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.23 (p 0.365, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.32 (p 0.198, n 18). could be the mix.
skeptic
leave-one-out range -0.41 to -0.13, sign flips 0; without severely affected donors -0.23 (p 0.355, n 18). fragile.
cell type
strongest in microglia: -0.61 (p 0.0077, n 18) vs -0.23 in dopamine neurons. proposing microglia.
axis
no measure beats "tracks Braak Lewy-body stage" for ADAM8 in dopamine neurons.

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