Swarm cases

receipt 12772: APBB2 in dopamine neurons, braak

power
full sample -0.29 (p 0.235, n 18), 95% CI -0.67 to +0.20. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.31 (p 0.218, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.30 (p 0.228, n 18). could be the mix.
skeptic
leave-one-out range -0.46 to -0.20, sign flips 0; without severely affected donors -0.29 (p 0.235, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for APBB2 in dopamine neurons.

case closed: nothing better to follow up.

receipt 12771: APBB2 in oligodendrocytes, braak

power
full sample +0.01 (p 0.956, n 18), 95% CI -0.46 to +0.48. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.01 (p 0.976, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.07 (p 0.774, n 18). could be the mix.
skeptic
leave-one-out range -0.13 to +0.12, sign flips 6; without severely affected donors +0.01 (p 0.956, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for APBB2 in oligodendrocytes.
