The swarm's case
receipt 1322: FASN in dopamine neurons, braak
- power
- full sample -0.09 (p 0.715, n 18), 95% CI -0.54 to +0.39. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: -0.08 (p 0.748, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.12 (p 0.633, n 18). could be the mix.
- skeptic
- leave-one-out range -0.18 to +0.03, sign flips 1; without severely affected donors -0.09 (p 0.715, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for FASN in dopamine neurons.
case closed: nothing better to follow up.
