Swarm cases

receipt 7227: PTPRQ in dopamine neurons, braak

power
full sample +0.53 (p 0.024, n 18), 95% CI +0.08 to +0.80. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: +0.48 (p 0.042, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.45 (p 0.062, n 18). could be the mix.
skeptic
leave-one-out range +0.47 to +0.69, sign flips 0; without severely affected donors +0.53 (p 0.024, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for PTPRQ in dopamine neurons.

case closed: nothing better to follow up.
