Swarm cases

receipt 1701: FFAR1 in dopamine neurons, braak

power
full sample -0.66 (p 0.0028, n 18), 95% CI -0.86 to -0.28. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.62 (p 0.0060, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.60 (p 0.0089, n 18). not the mix.
skeptic
leave-one-out range -0.75 to -0.62, sign flips 0; without severely affected donors -0.66 (p 0.0028, n 18). robust.
cell type
strongest in oligodendrocytes: -0.72 (p 7.4e-4, n 18) vs -0.66 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for FFAR1 in dopamine neurons.
