The swarm's case
receipt 4059: SELENOP in dopamine neurons, braak
- power
- full sample +0.51 (p 0.030, n 18), 95% CI +0.06 to +0.79. the interval excludes zero: something may be there, smaller than a half can see.
- confounder
- adjusted for sex: +0.44 (p 0.064, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.62 (p 0.0060, n 18). not the mix.
- skeptic
- leave-one-out range +0.46 to +0.75, sign flips 0; without severely affected donors +0.51 (p 0.030, n 18). robust.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for SELENOP in dopamine neurons.
case closed: nothing better to follow up.
