The swarm's case
receipt 0135: SCN1A in oligodendrocytes, 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: -0.07 (p 0.518, n 84). does not hold up.
- composition
- oligodendrocytes share of nuclei vs axis +0.09 (p 0.422); controlling for it: -0.08 (p 0.472, n 84). could be the mix.
- skeptic
- leave-one-out range -0.12 to -0.06, sign flips 0; without severely affected donors +0.04 (p 0.743, n 75). fragile.
- cell type
- strongest in GABA neurons: +0.31 (p 0.0040, n 84) vs -0.09 in oligodendrocytes. proposing GABA neurons.
- axis
- no measure beats "tracks Braak Lewy-body stage" for SCN1A in oligodendrocytes.
