60-day mortality of selective serotonin reuptake inhibitor (SSRI) users vs. non-SSRI users. Sixty-day mortality was analysed using the Kaplan–Meier method. Exposed = SSRI users; not exposed = non-SSRI users. Day zero was the date of the positive SARS-CoV-2 PCR test. SSRI use is defined as pharmacy pickups with sufficient daily dispensing to cover a period of at least two days prior to and 14 days after a positive SARS-CoV-2 PCR. The starting time for risk-time calculation was defined as the time of the positive PCR test. Data were obtained from Danish National Administrative registries available through Statistics Denmark; see the method section for details.
