The swarm's case

receipt 1160: FCRL2 in dopamine neurons, braak

power
full sample +0.48 (p 0.043, n 18), 95% CI +0.02 to +0.77. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: +0.45 (p 0.060, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.41 (p 0.091, n 18). could be the mix.
skeptic
leave-one-out range +0.43 to +0.67, sign flips 0; without severely affected donors +0.48 (p 0.043, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for FCRL2 in dopamine neurons.

case closed: nothing better to follow up.
