Figure 4

Weekly SRI versus Weekly Nap Duration between relapse and non-relapse. Weekly SRI and mean nap duration in individuals who relapsed (red) and those no did not (blue). The y-axis indicates the model predicted weekly SRI and the x-axis indicates the average nap duration over the group. The slope of the non-relapsed group is steeper indicating that napping had a higher impact on the SRI in individuals who did not relapse.
