The swarm's case
receipt 3217: ASPA in dopamine neurons, braak
- power
- full sample +0.03 (p 0.922, n 18), 95% CI -0.45 to +0.49. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: +0.05 (p 0.847, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.09 (p 0.715, n 18). could be the mix.
- skeptic
- leave-one-out range -0.09 to +0.13, sign flips 5; without severely affected donors +0.03 (p 0.922, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for ASPA in dopamine neurons.
case closed: nothing better to follow up.
