Table 2.
Results of the fully adjusted regression analysis on data from all participants (10,903 person-nights of data from 50 participants). TST is total sleep time, SE is sleep efficiency, and RSTLS is sleep restlessness. We did not report coefficients for environmental variables because they were modeled as non-linear predictors. Their predicted impact on outcomes is presented graphically in figure 7.
