Figure 2. Associations between serum amylase and mortality, as well as secondary outcomes. (A) Restricted cubic splines analysis illustrated the association between serum amylase and all cause mortality. (B) Kaplan-Meier curves for cumulative probability of COVID-19 mortality during hospitalization in patients with different level of serum amylase. (C) Multivariable mixed-effect logistic regression model indicated that hyperamylasemia was independently associated with sepsis, DIC, Cardiac injury, ARDS and AKI.
