The swarm's case

receipt 3309: DAGLB in microglia, braak

power
full sample +0.08 (p 0.761, n 18), 95% CI -0.40 to +0.53. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.07 (p 0.774, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: +0.21 (p 0.413, n 18). could be the mix.
skeptic
leave-one-out range -0.04 to +0.21, sign flips 2; without severely affected donors +0.08 (p 0.761, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for DAGLB in microglia.

case closed: nothing better to follow up.
