The swarm's case
receipt 9027: ISG15 in dopamine neurons, braak
- power
- full sample -0.23 (p 0.351, n 18), 95% CI -0.63 to +0.26. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: -0.22 (p 0.384, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.17 (p 0.504, n 18). could be the mix.
- skeptic
- leave-one-out range -0.37 to -0.11, sign flips 0; without severely affected donors -0.23 (p 0.351, n 18). fragile.
- cell type
- strongest in microglia: -0.60 (p 0.0089, n 18) vs -0.23 in dopamine neurons. proposing microglia.
- axis
- no measure beats "tracks Braak Lewy-body stage" for ISG15 in dopamine neurons.
