The swarm's case

receipt 2407: CTSD in dopamine neurons, braak

power
full sample +0.54 (p 0.021, n 18), 95% CI +0.10 to +0.80. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: +0.62 (p 0.0057, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.56 (p 0.016, n 18). not the mix.
skeptic
leave-one-out range +0.48 to +0.65, sign flips 0; without severely affected donors +0.54 (p 0.021, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for CTSD in dopamine neurons.

case closed: nothing better to follow up.
