Disclaimer: All calculations must be confirmed before use. This prognostic model was developed based on the isolated, left-sided CDH infants treated at high-volume facilities in Japan. The suggested results are only estimates and do not substitute for clinical judgment. Factors other than explanatory variables of our model also influence prognosis.
