The swarm's case
receipt 6167: TP53INP1 in dopamine neurons, braak
- power
- full sample -0.45 (p 0.059, n 18), 95% CI -0.76 to +0.02. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: -0.34 (p 0.161, n 18). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.38 (p 0.118, n 18). could be the mix.
- skeptic
- leave-one-out range -0.57 to -0.39, sign flips 0; without severely affected donors -0.45 (p 0.059, n 18). robust.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for TP53INP1 in dopamine neurons.
case closed: nothing better to follow up.
