The swarm's case

receipt 7841: ATP5F1C in dopamine neurons, braak

power
full sample +0.68 (p 0.0019, n 18), 95% CI +0.31 to +0.87. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: +0.70 (p 0.0013, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.80 (p 6.9e-5, n 18). not the mix.
skeptic
leave-one-out range +0.64 to +0.75, sign flips 0; without severely affected donors +0.68 (p 0.0019, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for ATP5F1C in dopamine neurons.

case closed: nothing better to follow up.
