Swarm cases

receipt 3455: XDH in dopamine neurons, braak

power
full sample +0.19 (p 0.460, n 18), 95% CI -0.31 to +0.60. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.18 (p 0.471, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.03 (p 0.908, n 18). could be the mix.
skeptic
leave-one-out range +0.09 to +0.33, sign flips 0; without severely affected donors +0.19 (p 0.460, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for XDH in dopamine neurons.

case closed: nothing better to follow up.
