Swarm cases

receipt 13368: GRAMD2B in dopamine neurons, braak

power
full sample +0.03 (p 0.901, n 18), 95% CI -0.44 to +0.49. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.06 (p 0.820, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.13 (p 0.615, n 18). could be the mix.
skeptic
leave-one-out range -0.05 to +0.18, sign flips 6; without severely affected donors +0.03 (p 0.901, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for GRAMD2B in dopamine neurons.

case closed: nothing better to follow up.

receipt 13367: GRAMD2B in astrocytes, braak

power
full sample +0.40 (p 0.103, n 18), 95% CI -0.09 to +0.73. the interval is wide: not enough donors to tell.

composition
astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: +0.38 (p 0.120, n 18). could be the mix.
skeptic
leave-one-out range +0.32 to +0.58, sign flips 0; without severely affected donors +0.40 (p 0.103, n 18). fragile.
cell type
no other cell group does better.
axis
