Swarm cases

receipt 8891: SERPINI1 in dopamine neurons, braak

power
full sample +0.37 (p 0.132, n 18), 95% CI -0.12 to +0.71. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.37 (p 0.132, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.35 (p 0.153, n 18). could be the mix.
skeptic
leave-one-out range +0.29 to +0.53, sign flips 0; without severely affected donors +0.37 (p 0.132, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for SERPINI1 in dopamine neurons.

case closed: nothing better to follow up.

receipt 8890: SERPINI1 in oligodendrocytes, braak

power
full sample +0.30 (p 0.225, n 18), 95% CI -0.19 to +0.67. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.34 (p 0.173, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.50 (p 0.034, n 18). not the mix.
skeptic
leave-one-out range +0.21 to +0.45, sign flips 0; without severely affected donors +0.30 (p 0.225, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for SERPINI1 in oligodendrocytes.
