The swarm's case

receipt 9433: TRIM25 in dopamine neurons, braak

power
full sample -0.38 (p 0.118, n 18), 95% CI -0.72 to +0.10. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.41 (p 0.089, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.43 (p 0.079, n 18). could be the mix.
skeptic
leave-one-out range -0.47 to -0.30, sign flips 0; without severely affected donors -0.38 (p 0.118, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for TRIM25 in dopamine neurons.

case closed: nothing better to follow up.
