 This study examined the correlation between certain risk factors and the severity of COVID-19 infections among patients admitted to Stanford Hospital. The results showed that low presenting oxygen saturation was associated with increased risk of developing more serious complications, such as pneumonia, ARDS, or ICU admittance. Additionally, hypertension was found to be correlated with higher rates of severe disease. These findings could help doctors quickly identify patients who are at high risk of developing severe symptoms so they can receive appropriate treatment. This article was authored by Samuel J. S.
