The swarm's case
receipt 4356: LAMC1 in dopamine neurons, braak
- power
- full sample +0.36 (p 0.140, n 18), 95% CI -0.13 to +0.71. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: +0.47 (p 0.049, n 18). holds up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.53 (p 0.022, n 18). not the mix.
- skeptic
- leave-one-out range +0.29 to +0.49, sign flips 0; without severely affected donors +0.36 (p 0.140, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for LAMC1 in dopamine neurons.
case closed: nothing better to follow up.
