Swarm cases

receipt 7861: ITIH4 in dopamine neurons, braak

power
full sample -0.24 (p 0.328, n 18), 95% CI -0.64 to +0.25. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.20 (p 0.434, 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 0.471, n 18). could be the mix.
skeptic
leave-one-out range -0.37 to -0.13, sign flips 0; without severely affected donors -0.24 (p 0.328, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for ITIH4 in dopamine neurons.

case closed: nothing better to follow up.

receipt 7860: ITIH4 in astrocytes, braak

power
full sample -0.52 (p 0.027, n 18), 95% CI -0.79 to -0.07. 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
astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: -0.48 (p 0.044, n 18). not the mix.
skeptic
leave-one-out range -0.65 to -0.46, sign flips 0; without severely affected donors -0.52 (p 0.027, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for ITIH4 in astrocytes.

case closed: nothing better to follow up.
