The swarm's case

receipt 13288: HLA-DOB in dopamine neurons, braak

power
full sample -0.30 (p 0.232, n 18), 95% CI -0.67 to +0.20. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.28 (p 0.254, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.58 (p 0.012, n 18). not the mix.
skeptic
leave-one-out range -0.40 to -0.21, sign flips 0; without severely affected donors -0.30 (p 0.232, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for HLA-DOB in dopamine neurons.

case closed: nothing better to follow up.
