Multivariable analysis including comorbidities and socio-economic variables. HR, hazard ratio; SSRI, selective serotonin reuptake inhibitor. CI₉₅, 95% confidence interval; s, male sex. The endpoint was all-cause mortality within 60 days after a positive SARS-CoV-2 PCR test. SSRI intake was 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 test. Hazard ratios were estimated with Cox regressions. For ethnicity, “Danish” serves as reference. For income, “lowest quartile” serves as reference. For education, “basic school” serves as reference. In case of missingness, cases were omitted from the analysis. Data were obtained from Danish National Administrative registries available through Statistics Denmark; see the method section for definitions and details.
