  1. aValues shown in the table are the means (95% confidence intervals) of the average daily pattern metric adjusted for wear time and demographic factors (age, gender, race/ethnicity, and education) and weighted to account for selection due to factors related to device-wear consent. P-values correspond to tests for differences in means across levels of the factors. The selection model used to generate weights was based on all covariates shown in Table 1. activPAL-wear participants missing covariates that were used in the selection model (N = 42 participants) were excluded from the above weighted summary table
