Kaplan Meier survival curves showing overall survival from the time of COVID-19 diagnosis among (A) all head and neck cancer patients, (B) those requiring hospital admission for 1 day or more, and (C) those requiring ICU admission at any point, censored at the time of death or last known follow-up. 30-day mortality estimates are shown with 95% confidence intervals. (D) Forest plot of factors associated with mortality or survival among COVID-19 positive head and neck cancer patients. Cox proportional hazard modeling was performed with values shown in log 10 scale. (*) p < 0.05 and (**) p < 0.01.
