Table 3. Univariate and multivariates regression analysis for recurrent stroke at 1 year in relation to PSD at 2 weeks.

Model	OR	95%CI
Unadjusted	1.55	1.10–2.18
Adjusted
Model 1*	1.56	1.10–2.20
Model 2†	1.49	1.03–2.15

PSD indicates poststroke depression.

^*: Adjusted by gender and age.

^†: Adjusted by gender, age, traditional risk factors for recurrent stroke (including hypertension, diabetes, hyperlipidemia, smoking, high alcohol consumption, personal history stroke, history cardiovascular disease). And other co-variates (including gender, history cardiac disease, NIHSS at admission, ischemic stroke, anti-platelet, lower lipid drug, anti-depressant drugs).

Among 1713 patients with stroke, there were 481 patients with PSD at 2 weeks and 58 cases of cumulative recurrent stroke at 1 year. There were 1232 patients without PSD at 2 weeks, among which, there were 100 cases of cumulative recurrent stroke.
