The swarm's case
receipt 2079: TTC6 in dopamine neurons, braak
- power
- full sample +0.48 (p 0.045, n 18), 95% CI +0.01 to +0.77. the interval excludes zero: something may be there, smaller than a half can see.
- confounder
- adjusted for sex: +0.41 (p 0.087, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.46 (p 0.054, n 18). could be the mix.
- skeptic
- leave-one-out range +0.41 to +0.69, sign flips 0; without severely affected donors +0.48 (p 0.045, n 18). robust.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for TTC6 in dopamine neurons.
case closed: nothing better to follow up.
