Swarm cases

receipt 10181: FFAR4 in dopamine neurons, braak

power
full sample -0.43 (p 0.077, n 18), 95% CI -0.75 to +0.05. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.43 (p 0.077, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.49 (p 0.037, n 18). not the mix.
skeptic
leave-one-out range -0.57 to -0.35, sign flips 0; without severely affected donors -0.43 (p 0.077, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for FFAR4 in dopamine neurons.

case closed: nothing better to follow up.

receipt 10180: FFAR4 in microglia, braak

power
full sample -0.47 (p 0.047, n 18), 95% CI -0.77 to -0.01. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.46 (p 0.054, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: -0.55 (p 0.018, n 18). not the mix.
skeptic
leave-one-out range -0.56 to -0.40, sign flips 0; without severely affected donors -0.47 (p 0.047, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for FFAR4 in microglia.

case closed: nothing better to follow up.
