Patients of all ages were recruited to the study. The patients with agreed diagnosis (diagnosed patients; n=794) included more pediatric (≤18 years) than adult (>18 years) patients (445 patients [56%] vs 349 [44%]). The age distribution was relatively uniform for patients aged 20-80 years and peaked at <4 years of age for pediatric patients (Fig.  S2) . The observed age distribution for pediatric patients is consistent with that expected and represents the background distribution in the inpatient setting [4] (e.g., the emergency department [ED], pediatrics departments, and internal departments). Patients of both genders were recruited to the study. The patient population was balanced in respect to gender distribution (47% females, 53% males).
