Swarm cases

receipt 5335: BARHL2 in dopamine neurons, braak

power
full sample -0.33 (p 0.182, n 18), 95% CI -0.69 to +0.16. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.22 (p 0.374, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.29 (p 0.250, n 18). could be the mix.
skeptic
leave-one-out range -0.49 to -0.23, sign flips 0; without severely affected donors -0.33 (p 0.182, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for BARHL2 in dopamine neurons.

case closed: nothing better to follow up.
