The swarm's case
receipt 0292: IGSF9B in oligodendrocytes, braak
- power
- full sample -0.27 (p 0.273, n 18), 95% CI -0.66 to +0.22. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: -0.28 (p 0.269, n 18). does not hold up.
- composition
- oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.43 (p 0.075, n 18). could be the mix.
- skeptic
- leave-one-out range -0.40 to -0.18, sign flips 0; without severely affected donors -0.27 (p 0.273, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for IGSF9B in oligodendrocytes.
case closed: nothing better to follow up.
