Swarm cases

receipt 6308: OR4D9 in dopamine neurons, braak

power
full sample +0.63 (p 0.0054, n 18), 95% CI +0.23 to +0.85. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: +0.56 (p 0.015, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.57 (p 0.013, n 18). not the mix.
skeptic
leave-one-out range +0.59 to +0.83, sign flips 0; without severely affected donors +0.63 (p 0.0054, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for OR4D9 in dopamine neurons.

case closed: nothing better to follow up.
