Swarm cases

receipt 7420: SAG in dopamine neurons, braak

power
full sample -0.37 (p 0.135, n 18), 95% CI -0.71 to +0.12. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.37 (p 0.135, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.45 (p 0.060, n 18). could be the mix.
skeptic
leave-one-out range -0.53 to -0.29, sign flips 0; without severely affected donors -0.37 (p 0.135, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for SAG in dopamine neurons.

case closed: nothing better to follow up.
