The swarm's case
receipt 5109: MAN2B1 in microglia, braak
- power
- full sample +0.02 (p 0.949, n 18), 95% CI -0.45 to +0.48. the interval is wide: not enough donors to tell.
- confounder
- adjusted for sex: -0.00 (p 0.997, n 18). does not hold up.
- composition
- microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: +0.15 (p 0.544, n 18). could be the mix.
- skeptic
- leave-one-out range -0.12 to +0.17, sign flips 5; without severely affected donors +0.02 (p 0.949, n 18). fragile.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for MAN2B1 in microglia.
case closed: nothing better to follow up.
