The swarm's case

receipt 10674: RPL10 in dopamine neurons, braak

power
full sample +0.40 (p 0.103, n 18), 95% CI -0.09 to +0.73. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.43 (p 0.072, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.48 (p 0.045, n 18). not the mix.
skeptic
leave-one-out range +0.32 to +0.47, sign flips 0; without severely affected donors +0.40 (p 0.103, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for RPL10 in dopamine neurons.

case closed: nothing better to follow up.
