Swarm cases

receipt 2601: CACNA1D in dopamine neurons, braak

power
full sample -0.20 (p 0.418, n 18), 95% CI -0.61 to +0.29. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.16 (p 0.526, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.35 (p 0.153, n 18). could be the mix.
skeptic
leave-one-out range -0.33 to -0.10, sign flips 0; without severely affected donors -0.20 (p 0.418, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for CACNA1D in dopamine neurons.

case closed: nothing better to follow up.
