Recurrence of depression in patients with incident PSD at 1-year and recovered at 2-years after stroke.
| Recurrent Time (Time since stroke) | Recurrent Time (Time since recovery) | Patients with incident depression at 1-year had assessment of recurrence at any time-point | Patients with incident depression at 1-year had depression recurred at any time-point | Cumulative recurrence rate of depression at each time-point | Patients with mild incident depression at 1-year had assessment of recurrence at any time-point | Patients with mild incident depression at 1-year had depression recurred at any time-point | Cumulative recurrence rate of depression in patients with mild depression | Patients with severe incident depression at 1-year had assessment of recurrence at any time-point | Patients with severe incident depression at 1-year had depression recurred at any time-point | Cumulative recurrence rate of depression in patients with severe depression |

Notes: Among all the recurrences of depression, 90.2% (46/51) (95% CI: 78.6–96.7) 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.
