The swarm's case

receipt 5244: DGKG in oligodendrocytes, braak

power
full sample -0.36 (p 0.140, n 18), 95% CI -0.71 to +0.13. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.31 (p 0.204, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.53 (p 0.023, n 18). not the mix.
skeptic
leave-one-out range -0.51 to -0.28, sign flips 0; without severely affected donors -0.36 (p 0.140, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for DGKG in oligodendrocytes.

case closed: nothing better to follow up.
