Swarm cases

receipt 1508: PPP1R3B in dopamine neurons, braak

power
full sample -0.47 (p 0.050, n 18), 95% CI -0.77 to -0.00. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.47 (p 0.051, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.44 (p 0.066, n 18). could be the mix.
skeptic
leave-one-out range -0.63 to -0.40, sign flips 0; without severely affected donors -0.47 (p 0.050, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for PPP1R3B in dopamine neurons.

case closed: nothing better to follow up.

receipt 1507: PPP1R3B in microglia, braak

power
full sample +0.08 (p 0.748, n 18), 95% CI -0.40 to +0.53. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.08 (p 0.754, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: +0.27 (p 0.273, n 18). could be the mix.
skeptic
leave-one-out range -0.02 to +0.24, sign flips 2; without severely affected donors +0.08 (p 0.748, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for PPP1R3B in microglia.

case closed: nothing better to follow up.
