The swarm's case

receipt 7675: CTSK in dopamine neurons, braak

power
full sample +0.61 (p 0.0075, n 18), 95% CI +0.20 to +0.84. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: +0.61 (p 0.0077, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.61 (p 0.0067, n 18). not the mix.
skeptic
leave-one-out range +0.56 to +0.74, sign flips 0; without severely affected donors +0.61 (p 0.0075, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for CTSK in dopamine neurons.

case closed: nothing better to follow up.
