The swarm's case

receipt 11722: TP53BP1 in dopamine neurons, braak

power
full sample -0.09 (p 0.728, n 18), 95% CI -0.53 to +0.40. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.11 (p 0.658, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.06 (p 0.827, n 18). could be the mix.
skeptic
leave-one-out range -0.23 to +0.02, sign flips 1; without severely affected donors -0.09 (p 0.728, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for TP53BP1 in dopamine neurons.

case closed: nothing better to follow up.
