Swarm cases

receipt 2502: GRIK2 in dopamine neurons, braak

power
full sample +0.44 (p 0.069, n 18), 95% CI -0.04 to +0.75. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.47 (p 0.050, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.49 (p 0.041, n 18). not the mix.
skeptic
leave-one-out range +0.36 to +0.65, sign flips 0; without severely affected donors +0.44 (p 0.069, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for GRIK2 in dopamine neurons.

case closed: nothing better to follow up.
