Swarm cases

receipt 5441: ATG4B in dopamine neurons, braak

power
full sample -0.28 (p 0.261, n 18), 95% CI -0.66 to +0.22. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.26 (p 0.298, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.28 (p 0.258, n 18). could be the mix.
skeptic
leave-one-out range -0.36 to -0.17, sign flips 0; without severely affected donors -0.28 (p 0.261, n 18). fragile.
cell type
strongest in astrocytes: -0.62 (p 0.0062, n 18) vs -0.28 in dopamine neurons. proposing astrocytes.
axis
