Swarm cases

receipt 1121: FCGR2A in dopamine neurons, braak

power
full sample +0.01 (p 0.956, n 18), 95% CI -0.46 to +0.48. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.01 (p 0.983, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.03 (p 0.922, n 18). could be the mix.
skeptic
leave-one-out range -0.09 to +0.12, sign flips 7; without severely affected donors +0.01 (p 0.956, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for FCGR2A in dopamine neurons.

case closed: nothing better to follow up.
