Swarm cases

receipt 14109: GPS2 in dopamine neurons, braak

cell type
GPS2 is not measured in dopamine neurons; looking elsewhere.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for GPS2 in dopamine neurons.

case closed: nothing better to follow up.

receipt 14108: GPS2 in oligodendrocytes, braak

power
full sample +0.26 (p 0.298, n 18), 95% CI -0.24 to +0.65. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.28 (p 0.269, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.40 (p 0.101, n 18). could be the mix.
skeptic
leave-one-out range +0.16 to +0.34, sign flips 0; without severely affected donors +0.26 (p 0.298, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for GPS2 in oligodendrocytes.

case closed: nothing better to follow up.
