Swarm cases

receipt 11825: GREM1 in dopamine neurons, braak

power
full sample +0.20 (p 0.418, n 18), 95% CI -0.29 to +0.61. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.13 (p 0.609, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.14 (p 0.585, n 18). could be the mix.
skeptic
leave-one-out range +0.11 to +0.30, sign flips 0; without severely affected donors +0.20 (p 0.418, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for GREM1 in dopamine neurons.

case closed: nothing better to follow up.

receipt 11824: GREM1 in oligodendrocytes, braak

power
full sample -0.02 (p 0.942, n 18), 95% CI -0.48 to +0.45. 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: -0.19 (p 0.460, n 18). could be the mix.
skeptic
leave-one-out range -0.14 to +0.10, sign flips 5; without severely affected donors -0.02 (p 0.942, n 18). fragile.
cell type
