The swarm's case
receipt 9570: ISCU in dopamine neurons, braak
- power
- full sample -0.08 (p 0.741, n 18), 95% CI -0.53 to +0.40. 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: -0.14 (p 0.579, n 18). could be the mix.
- skeptic
- leave-one-out range -0.19 to +0.05, sign flips 3; without severely affected donors -0.08 (p 0.741, n 18). fragile.
- cell type
- strongest in microglia: +0.64 (p 0.0039, n 18) vs -0.08 in dopamine neurons. proposing microglia.
- axis
- no measure beats "tracks Braak Lewy-body stage" for ISCU in dopamine neurons.
