Swarm cases

receipt 4679: IL13RA1 in dopamine neurons, braak

power
full sample +0.14 (p 0.567, n 18), 95% CI -0.35 to +0.57. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.27 (p 0.281, 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 0.315, n 18). could be the mix.
skeptic
leave-one-out range +0.03 to +0.31, sign flips 0; without severely affected donors +0.14 (p 0.567, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for IL13RA1 in dopamine neurons.

case closed: nothing better to follow up.

receipt 4678: IL13RA1 in microglia, braak

power
full sample +0.38 (p 0.120, n 18), 95% CI -0.11 to +0.72. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.38 (p 0.120, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: +0.38 (p 0.123, n 18). could be the mix.
skeptic
leave-one-out range +0.30 to +0.49, sign flips 0; without severely affected donors +0.38 (p 0.120, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for IL13RA1 in microglia.
