The swarm's case
receipt 0099: ITPKB in astrocytes, braak
- power
- full sample -0.11 (p 0.302, n 84), 95% CI -0.32 to +0.10. the interval sits on zero: probably nothing there.
- confounder
- adjusted for age, sex and PMI: -0.05 (p 0.658, n 84). does not hold up.
- composition
- astrocytes share of nuclei vs axis +0.26 (p 0.016); controlling for it: -0.08 (p 0.486, n 84). could be the mix.
- skeptic
- leave-one-out range -0.15 to -0.09, sign flips 0; without severely affected donors -0.13 (p 0.269, n 75). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for ITPKB in astrocytes.
case closed: nothing better to follow up.
