Recurrence of depression in patients with PSD at 3-months and recovered at 1-year after stroke.
| Recurrent Time (Time since stroke) | Recurrent Time (Time since recovery) | Patients with depression at 3-months had assessment of recurrence at any time-point | Patients with depression at 3-months had depression recurred at any time-point | Cumulative recurrence rate of depression at each time-point | Patients with mild depression at 3-months had assessment of recurrence at any time-point | Patients with mild depression at 3-months had depression recurred at any time-point | Cumulative recurrence rate of depression in patients with mild depression | Patients with severe depression at 3-months had assessment of recurrence at any time-point | Patients with severe depression at 3-months had depression recurred at any time-point | Cumulative recurrence rate of depression in patients with severe depression |

Notes: Among all the recurrences of depression, 94.4% (85/90) (95% CI: 87.5%–98.2%) occurred within 5-years since recovery.
a
Two proportional Z test was used to compare the recurrence rates between mild and severe depression, a means p < 0.05.
