    a) Overall survival probability for individuals positive for SARS-CoV-2 in Tayside, Scotland based on the cycle threshold (Ct) value of their first positive test. Crosses represent censored individuals. b) Estimated hazard ratio (HR) based on initial Ct value of individual in a model adjusting for age, sex, hypertension, heart failure, ischaemic heart disease, COPD, asthma, chronic kidney disease and type 2 diabetes mellitus.
