Swarm cases

receipt 1436: JAK2 in dopamine neurons, braak

power
full sample +0.35 (p 0.159, n 18), 95% CI -0.14 to +0.70. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.31 (p 0.218, 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 +0.30 to +0.55, sign flips 0; without severely affected donors +0.35 (p 0.159, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for JAK2 in dopamine neurons.

case closed: nothing better to follow up.

receipt 1435: JAK2 in microglia, braak

power
full sample -0.43 (p 0.079, n 18), 95% CI -0.74 to +0.05. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.38 (p 0.116, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: -0.42 (p 0.084, n 18). could be the mix.
skeptic
leave-one-out range -0.50 to -0.34, sign flips 0; without severely affected donors -0.43 (p 0.079, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for JAK2 in microglia.

case closed: nothing better to follow up.
