The swarm's case
receipt 11311: NDRG2 in astrocytes, braak
- power
- full sample +0.06 (p 0.800, n 18), 95% CI -0.42 to +0.52. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: +0.10 (p 0.696, n 18). does not hold up.
- composition
- astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: +0.10 (p 0.696, n 18). could be the mix.
- skeptic
- leave-one-out range -0.09 to +0.15, sign flips 3; without severely affected donors +0.06 (p 0.800, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for NDRG2 in astrocytes.
case closed: nothing better to follow up.
