The swarm's case
receipt 5367: IL33 in dopamine neurons, braak
- power
- full sample +0.09 (p 0.728, n 18), 95% CI -0.40 to +0.53. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: +0.11 (p 0.652, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.13 (p 0.609, n 18). could be the mix.
- skeptic
- leave-one-out range -0.02 to +0.21, sign flips 3; without severely affected donors +0.09 (p 0.728, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for IL33 in dopamine neurons.
case closed: nothing better to follow up.
