Swarm cases

receipt 4212: SEMA3A in dopamine neurons, braak

power
full sample +0.46 (p 0.057, n 18), 95% CI -0.01 to +0.76. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.46 (p 0.054, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.53 (p 0.023, n 18). not the mix.
skeptic
leave-one-out range +0.38 to +0.63, sign flips 0; without severely affected donors +0.46 (p 0.057, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for SEMA3A in dopamine neurons.

case closed: nothing better to follow up.
