The swarm's case

receipt 11779: OGFR in dopamine neurons, braak

power
full sample -0.51 (p 0.032, n 18), 95% CI -0.79 to -0.05. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.47 (p 0.050, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.47 (p 0.050, n 18). not the mix.
skeptic
leave-one-out range -0.58 to -0.46, sign flips 0; without severely affected donors -0.51 (p 0.032, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for OGFR in dopamine neurons.

case closed: nothing better to follow up.
