Swarm cases

receipt 5638: RAB3A in dopamine neurons, braak

power
full sample -0.42 (p 0.084, n 18), 95% CI -0.74 to +0.06. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.51 (p 0.032, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.60 (p 0.0089, n 18). not the mix.
skeptic
leave-one-out range -0.53 to -0.35, sign flips 0; without severely affected donors -0.42 (p 0.084, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for RAB3A in dopamine neurons.

case closed: nothing better to follow up.
