The swarm's case
receipt 0091: GRIN3B in dopamine neurons, braak
- power
- full sample +0.15 (p 0.180, n 84), 95% CI -0.07 to +0.35. the interval sits on zero: probably nothing there.
- confounder
- adjusted for age, sex and PMI: +0.13 (p 0.243, n 84). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis -0.72 (p 1.8e-14); controlling for it: +0.12 (p 0.273, n 84). could be the mix.
- skeptic
- leave-one-out range +0.12 to +0.19, sign flips 0; without severely affected donors +0.17 (p 0.156, n 75). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for GRIN3B in dopamine neurons.
case closed: nothing better to follow up.
