Swarm cases

receipt 6798: CASP8 in dopamine neurons, braak

power
full sample +0.03 (p 0.915, n 18), 95% CI -0.45 to +0.49. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.02 (p 0.928, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.02 (p 0.942, n 18). could be the mix.
skeptic
leave-one-out range -0.04 to +0.16, sign flips 7; without severely affected donors +0.03 (p 0.915, n 18). fragile.
cell type
strongest in microglia: -0.65 (p 0.0034, n 18) vs +0.03 in dopamine neurons. proposing microglia.
axis
