The multivariable analysis identified risk factors for stroke recurrence including history of previous stroke (HR = 3.65, 95% CI:2.28–5.99, p = 0.0001), tissue plasminogen activator (tPA) treatment (HR = 2.84, 95% CI:1.57–4.86, p = 0.0003), seizure (HR = 1.96, 95% CI:1.14–3.22, p = 0.0105), and depression (HR = 2.26, 95% CI:1.33–3.69, p = 0.0016). The gene discussed is PLAT; the disease is major depressive disorder.
