Swarm cases

receipt 13903: GCNT2 in dopamine neurons, braak

power
full sample +0.09 (p 0.728, n 18), 95% CI -0.40 to +0.53. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.01 (p 0.962, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.03 (p 0.894, n 18). could be the mix.
skeptic
leave-one-out range -0.05 to +0.23, sign flips 3; without severely affected donors +0.09 (p 0.728, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for GCNT2 in dopamine neurons.

case closed: nothing better to follow up.

receipt 13902: GCNT2 in microglia, braak

power
full sample +0.10 (p 0.683, n 18), 95% CI -0.38 to +0.54. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.06 (p 0.827, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: -0.09 (p 0.722, n 18). could be the mix.
skeptic
leave-one-out range -0.02 to +0.26, sign flips 1; without severely affected donors +0.10 (p 0.683, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for GCNT2 in microglia.
