A summary of model outcomes in predicting mean physical activity during the second half of the day (noon to 11pm).

SQ = Sleep quality; A-SE = actigraphy sleep efficiency; SE = diary sleep efficiency; n/a = not applicable.LRT = Likelihood Ratio Test, which assessed the significance of each predictor of interest (e.g., SQ) by comparing the alternative model (e.g., SQ + C; –Log Likelihood = 4597) with the appropriate null model with only a constant term. The p value adjacent indicated whether the alternative model was significantly better.AIC = Akiake Information Criterion, unlike LRT, compared the alternative models directly (e.g., SQ + C versus A-SE + C), taking into account each model’s complexity. Smaller AIC values indicate better models, but the absolute sizes of the AIC values are not informative. Instead the difference between them indicates the relative strength of predictors, which were then assessed in the form of relative probabilities, where larger values are better.
