Swarm cases

receipt 3922: SYNGAP1 in dopamine neurons, braak

power
full sample -0.54 (p 0.021, n 18), 95% CI -0.80 to -0.10. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.53 (p 0.024, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.69 (p 0.0015, n 18). not the mix.
skeptic
leave-one-out range -0.65 to -0.48, sign flips 0; without severely affected donors -0.54 (p 0.021, n 18). robust.
cell type
strongest in oligodendrocytes: -0.74 (p 5.0e-4, n 18) vs -0.54 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for SYNGAP1 in dopamine neurons.
