Protective effects of statins on COVID-19 risk, severity and fatal outcome: a nationwide Swedish cohort study.

ABSTRACT: The impact of statins on COVID-19 remains unclear. This study aims to investigate whether statin exposure assessed both in the population and in well-defined cohorts of COVID-19 patients may affect the risk and severity of COVID-19 using nationwide Swedish population-based register data.
