The swarm's case

receipt 4727: MERTK in microglia, braak

power
full sample -0.13 (p 0.603, n 18), 95% CI -0.56 to +0.36. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.05 (p 0.847, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: -0.06 (p 0.820, n 18). could be the mix.
skeptic
leave-one-out range -0.27 to -0.03, sign flips 0; without severely affected donors -0.13 (p 0.603, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for MERTK in microglia.

case closed: nothing better to follow up.
