Dose-response relationship between nighttime sleep duration and depression in the elderly.
The x-axis represents nighttime sleep duration in hours. The y-axis indicates the β-value calculated by the model. The shadowed area represents the 95% confidence interval (test for overall trend: P < 0.001; test for nonlinear trend: P < 0.001).
