Swarm cases

receipt 1933: ABL2 in dopamine neurons, braak

power
full sample +0.42 (p 0.084, n 18), 95% CI -0.06 to +0.74. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.52 (p 0.028, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.46 (p 0.056, n 18). could be the mix.
skeptic
leave-one-out range +0.34 to +0.56, sign flips 0; without severely affected donors +0.42 (p 0.084, n 18). robust.
cell type
strongest in OPCs: -0.67 (p 0.0022, n 18) vs +0.42 in dopamine neurons. proposing OPCs.
axis
