Swarm cases

receipt 2298: PLXNA1 in dopamine neurons, braak

power
full sample -0.43 (p 0.077, n 18), 95% CI -0.75 to +0.05. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.43 (p 0.077, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.56 (p 0.017, n 18). not the mix.
skeptic
leave-one-out range -0.54 to -0.35, sign flips 0; without severely affected donors -0.43 (p 0.077, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for PLXNA1 in dopamine neurons.

case closed: nothing better to follow up.
