Swarm cases

receipt 4874: CARNS1 in dopamine neurons, braak

power
full sample +0.11 (p 0.658, n 18), 95% CI -0.37 to +0.55. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.10 (p 0.690, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.16 (p 0.526, n 18). could be the mix.
skeptic
leave-one-out range -0.01 to +0.23, sign flips 2; without severely affected donors +0.11 (p 0.658, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for CARNS1 in dopamine neurons.

case closed: nothing better to follow up.
