The swarm's case

receipt 15703: MYO19 in dopamine neurons, braak

power
full sample -0.34 (p 0.167, n 18), 95% CI -0.70 to +0.15. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.34 (p 0.173, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.42 (p 0.082, n 18). could be the mix.
skeptic
leave-one-out range -0.48 to -0.25, sign flips 0; without severely affected donors -0.34 (p 0.167, n 18). fragile.
cell type
strongest in OPCs: -0.75 (p 3.7e-4, n 18) vs -0.34 in dopamine neurons. proposing OPCs.
axis
no measure beats "tracks Braak Lewy-body stage" for MYO19 in dopamine neurons.
