Swarm cases

receipt 5253: FAM20C in dopamine neurons, braak

power
full sample -0.49 (p 0.037, n 18), 95% CI -0.78 to -0.04. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.49 (p 0.040, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.70 (p 0.0011, n 18). not the mix.
skeptic
leave-one-out range -0.63 to -0.43, sign flips 0; without severely affected donors -0.49 (p 0.037, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for FAM20C in dopamine neurons.

case closed: nothing better to follow up.

receipt 5252: FAM20C in oligodendrocytes, braak

power
full sample -0.46 (p 0.052, n 18), 95% CI -0.77 to +0.00. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.45 (p 0.063, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.45 (p 0.063, n 18). could be the mix.
skeptic
leave-one-out range -0.62 to -0.40, sign flips 0; without severely affected donors -0.46 (p 0.052, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for FAM20C in oligodendrocytes.

case closed: nothing better to follow up.
