The swarm's case
receipt 10575: PSMB1 in dopamine neurons, braak
- power
- full sample +0.64 (p 0.0042, n 18), 95% CI +0.25 to +0.85. the interval excludes zero: something may be there, smaller than a half can see.
- confounder
- adjusted for sex: +0.66 (p 0.0031, n 18). holds up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.69 (p 0.0014, n 18). not the mix.
- skeptic
- leave-one-out range +0.59 to +0.77, sign flips 0; without severely affected donors +0.64 (p 0.0042, n 18). robust.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for PSMB1 in dopamine neurons.
case closed: nothing better to follow up.
