From: Non-linear relationship between social jetlag and depressive symptoms among Chinese college students

The exposure-response relationships between social jetlag and odd ratio of depressive symptoms among college students. The red solid line represents the odds ratio (OR) of depressive symptoms as a function of social jetlag, while the shaded area indicates the 95% confidence interval. The dashed red vertical line marks a social jetlag of 1.2 h, indicating an increased risk threshold. The black dashed horizontal line represents an odds ratio of 1, indicating no increased or decreased risk.
