The swarm's case

receipt 5077: CSF1 in dopamine neurons, braak

power
full sample -0.57 (p 0.013, n 18), 95% CI -0.82 to -0.14. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.63 (p 0.0053, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.67 (p 0.0022, n 18). not the mix.
skeptic
leave-one-out range -0.72 to -0.52, sign flips 0; without severely affected donors -0.57 (p 0.013, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for CSF1 in dopamine neurons.

case closed: nothing better to follow up.
