The swarm's case
receipt 1852: ADH1C in dopamine neurons, braak
- power
- full sample +0.21 (p 0.398, n 18), 95% CI -0.28 to +0.62. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: +0.21 (p 0.398, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.18 (p 0.471, n 18). could be the mix.
- skeptic
- leave-one-out range +0.12 to +0.40, sign flips 0; without severely affected donors +0.21 (p 0.398, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for ADH1C in dopamine neurons.
case closed: nothing better to follow up.
