Figure 6. — Model predictions for both CBT_min and DLMO. (A and C) The model-predicted CBT_min and DLMO times (CBT_min^p and DLMO^p) show a significant positive relationship with CBT_min and DLMO, respectively. (B and D) When correcting the model predictions of CBT_min and DLMO for activity acrophase (CBT_min^p+φ and DLMO^p+φ, respectively), 15% more variance in CBT_min and 19% more variance in DLMO were explained. The residual standard deviations corresponding to the regression analyses presented in panels A, B, C, and D were 1.46, 1.24, 1.4 and 1.1 h, respectively.
