Adjusted odds ratios of SARS-CoV-2 positivity according to prescription drug use.
Adjusted odds ratios for having a positive SARS-CoV-2 test (PCR or ELISA) according to use of prescription drugs (yes/no) in the six months before date of infection, compared to controls matched on sex, age and chronic diseases. Prescription drug categories are based on the Anatomical Therapeutic Chemical Classification System as defined by the World Health Organization (codes are listed in parenthesis).
