The swarm's case

receipt 1244: STAT3 in dopamine neurons, braak

power
full sample +0.08 (p 0.754, n 18), 95% CI -0.40 to +0.53. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.08 (p 0.754, 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 0.901, n 18). could be the mix.
skeptic
leave-one-out range -0.02 to +0.20, sign flips 2; without severely affected donors +0.08 (p 0.754, n 18). fragile.
cell type
strongest in oligodendrocytes: -0.62 (p 0.0057, n 18) vs +0.08 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for STAT3 in dopamine neurons.
