Swarm cases

receipt 2780: TMEM255B in dopamine neurons, braak

power
full sample -0.27 (p 0.285, n 18), 95% CI -0.65 to +0.23. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.30 (p 0.225, 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 0.221, n 18). could be the mix.
skeptic
leave-one-out range -0.40 to -0.17, sign flips 0; without severely affected donors -0.27 (p 0.285, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for TMEM255B in dopamine neurons.

case closed: nothing better to follow up.

receipt 2779: TMEM255B in microglia, braak

power
full sample -0.02 (p 0.928, n 18), 95% CI -0.48 to +0.45. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.08 (p 0.767, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: -0.03 (p 0.901, n 18). could be the mix.
skeptic
leave-one-out range -0.14 to +0.11, sign flips 7; without severely affected donors -0.02 (p 0.928, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for TMEM255B in microglia.
