Swarm cases

receipt 12307: P2RY13 in dopamine neurons, braak

power
full sample +0.18 (p 0.487, n 18), 95% CI -0.32 to +0.59. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.11 (p 0.652, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.18 (p 0.476, n 18). could be the mix.
skeptic
leave-one-out range +0.07 to +0.31, sign flips 0; without severely affected donors +0.18 (p 0.487, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for P2RY13 in dopamine neurons.

case closed: nothing better to follow up.

receipt 12306: P2RY13 in microglia, braak

power
full sample +0.43 (p 0.072, n 18), 95% CI -0.04 to +0.75. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.48 (p 0.046, n 18). holds up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: +0.61 (p 0.0075, n 18). not the mix.
skeptic
leave-one-out range +0.36 to +0.59, sign flips 0; without severely affected donors +0.43 (p 0.072, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for P2RY13 in microglia.

case closed: nothing better to follow up.
