The swarm's case

receipt 9942: KCNIP3 in oligodendrocytes, braak

power
full sample -0.47 (p 0.047, n 18), 95% CI -0.77 to -0.01. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.48 (p 0.043, n 18). holds up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.44 (p 0.070, n 18). could be the mix.
skeptic
leave-one-out range -0.61 to -0.41, sign flips 0; without severely affected donors -0.47 (p 0.047, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for KCNIP3 in oligodendrocytes.

case closed: nothing better to follow up.
