  1. CI confidence interval, EMR electronic medical record, N number of individuals, NPV negative predictive value, PPV positive predictive value, UEA ultrasound enhancing agents
  2. Shown are the number of individuals with UEA receipt in electronic medical record and claims data as well as the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of claims to identify UEA receipt in linked EMR and claims data. Results are stratified by point of service for the index echocardiogram, either during an inpatient hospitalization (inpatients) or in an outpatient facility or clinic (outpatients). Only UEA claims falling within 1-day of the date of service for the index echocardiogram are considered
