Swarm cases

receipt 0984: ITGB4 in dopamine neurons, braak

power
full sample -0.62 (p 0.0062, n 18), 95% CI -0.84 to -0.21. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.64 (p 0.0040, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.70 (p 0.0012, n 18). not the mix.
skeptic
leave-one-out range -0.75 to -0.57, sign flips 0; without severely affected donors -0.62 (p 0.0062, n 18). robust.
cell type
strongest in microglia: -0.67 (p 0.0022, n 18) vs -0.62 in dopamine neurons. proposing microglia.
axis
no measure beats "tracks Braak Lewy-body stage" for ITGB4 in dopamine neurons.
