The swarm's case

receipt 12432: PLEC in dopamine neurons, braak

power
full sample -0.58 (p 0.012, n 18), 95% CI -0.82 to -0.15. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.59 (p 0.010, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.72 (p 8.2e-4, n 18). not the mix.
skeptic
leave-one-out range -0.69 to -0.52, sign flips 0; without severely affected donors -0.58 (p 0.012, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for PLEC in dopamine neurons.

case closed: nothing better to follow up.
