Values that reach statistical significance (α < .05) are highlighted in red. Values of Pseudo R2 Change are calculated in comparison to the sleep stage model for individual measures and in comparison to the model containing TRC and sleep stage for the composite ones. Where applicable, Pseudo R2 Change and p-values reflect the contribution of the predictor highlighted in bold.
