The swarm's case
receipt 10308: FLT3 in dopamine neurons, braak
- power
- full sample -0.02 (p 0.935, n 18), 95% CI -0.48 to +0.45. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: -0.01 (p 0.976, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.01 (p 0.956, n 18). could be the mix.
- skeptic
- leave-one-out range -0.12 to +0.10, sign flips 5; without severely affected donors -0.02 (p 0.935, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for FLT3 in dopamine neurons.
case closed: nothing better to follow up.
