Table 2. Associations between schizophrenia polygenic risk (pT 0.05) and sleep outcomes.
| Sleep phenotype (units) | Beta or OR | 95% CI | R-squared 1 | P-value |
|---|---|---|---|---|
| Sleep duration in children (seconds) | -44.52 | -88.98, -0.07 | 0.0002 | 0.05 |
| Nightmares in children (ordinal, OR) | 1.08 | 1.01, 1.14 | 0.001 | 0.02 |
| Sleep duration in mothers (seconds) | -57.90 | -186.59, 70.76 | 0.00004 | 0.34 |
1The r-squared values were a marginal r-squared (the proportion of variance explained by the fixed effects) for sleep duration in children, Nagelkerke’s pseudo r-squared for nightmares and the adjusted r-squared for sleep duration in mothers.
