The swarm's case
receipt 11651: ADARB2 in dopamine neurons, braak
- power
- full sample -0.29 (p 0.243, n 18), 95% CI -0.67 to +0.20. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: -0.36 (p 0.145, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.44 (p 0.064, n 18). could be the mix.
- skeptic
- leave-one-out range -0.40 to -0.21, sign flips 0; without severely affected donors -0.29 (p 0.243, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for ADARB2 in dopamine neurons.
case closed: nothing better to follow up.
