The swarm's case
receipt 8794: TRPM3 in dopamine neurons, braak
- power
- full sample +0.19 (p 0.460, n 18), 95% CI -0.31 to +0.60. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: +0.14 (p 0.567, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.07 (p 0.794, n 18). could be the mix.
- skeptic
- leave-one-out range +0.12 to +0.36, sign flips 0; without severely affected donors +0.19 (p 0.460, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for TRPM3 in dopamine neurons.
case closed: nothing better to follow up.
