The swarm's case

receipt 9938: DOCK2 in dopamine neurons, braak

power
full sample -0.19 (p 0.444, n 18), 95% CI -0.60 to +0.30. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.24 (p 0.346, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.50 (p 0.036, n 18). not the mix.
skeptic
leave-one-out range -0.33 to -0.09, sign flips 0; without severely affected donors -0.19 (p 0.444, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for DOCK2 in dopamine neurons.

case closed: nothing better to follow up.
