The swarm's case
receipt 0124: CHRM3 in dopamine neurons, braak
- power
- full sample -0.09 (p 0.418, n 84), 95% CI -0.30 to +0.13. the interval sits on zero: probably nothing there.
- confounder
- adjusted for age, sex and PMI: -0.05 (p 0.621, n 84). does not hold up.
- composition
- dopamine neurons share of nuclei vs axis -0.72 (p 1.8e-14); controlling for it: -0.04 (p 0.743, n 84). could be the mix.
- skeptic
- leave-one-out range -0.12 to -0.06, sign flips 0; without severely affected donors -0.08 (p 0.474, n 75). fragile.
- cell type
- strongest in glutamate neurons: +0.52 (p 3.2e-7, n 84) vs -0.09 in dopamine neurons. proposing glutamate neurons.
- axis
- no measure beats "tracks Braak Lewy-body stage" for CHRM3 in dopamine neurons.
follow-up confirmed in ventral tegmental area.
