Swarm cases

receipt 10007: GNA13 in dopamine neurons, braak

power
full sample -0.28 (p 0.261, n 18), 95% CI -0.66 to +0.22. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.34 (p 0.161, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.22 (p 0.384, n 18). could be the mix.
skeptic
leave-one-out range -0.47 to -0.18, sign flips 0; without severely affected donors -0.28 (p 0.261, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for GNA13 in dopamine neurons.

case closed: nothing better to follow up.
