The swarm's case

receipt 0069: GRIN2C in astrocytes, resilience

power
full sample +0.10 (p 0.628, n 55), 95% CI -0.17 to +0.35. the interval is wide: not enough donors to tell.
confounder
adjusted for age, sex and PMI: +0.10 (p 0.628, n 55). does not hold up.
composition
astrocytes share of nuclei vs axis +0.34 (p 0.084); controlling for it: +0.07 (p 0.736, n 55). could be the mix.
skeptic
leave-one-out range +0.01 to +0.19, sign flips 0; without severely affected donors +0.09 (p 0.671, n 46). fragile.
cell type
no other cell group does better.
axis
no measure beats "differs in resilient donors (Lewy pathology, no parkinsonism)" for GRIN2C in astrocytes.

case closed: nothing better to follow up.
