Relationship of Morning Cortisol to Circadian Phase and Rising Time in Young Adults with Delayed Sleep Times
Figure 2
Peak cortisol time plotted as a function of circadian phase, DLMO (top row), and as a function of rising time (middle row), as well as DLMO plotted as a function of rising time (bottom row) on week 1 (left column) and on week 2 (right column). The data from the baseline week for one subject, the circled points in the left column of plots, were omitted from the regression analyses; see text.
