Swarm cases

receipt 14670: FAM13A in dopamine neurons, braak

power
full sample +0.10 (p 0.690, n 18), 95% CI -0.38 to +0.54. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.24 (p 0.328, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.25 (p 0.319, n 18). could be the mix.
skeptic
leave-one-out range -0.04 to +0.23, sign flips 3; without severely affected donors +0.10 (p 0.690, n 18). fragile.
cell type
strongest in OPCs: +0.63 (p 0.0055, n 18) vs +0.10 in dopamine neurons. proposing OPCs.
axis
no measure beats "tracks Braak Lewy-body stage" for FAM13A in dopamine neurons.

follow-up registered; not confirmed in substantia nigra, an independent cohort.
