*The example is an expert search that retrieves interventional trials with neonates, investigating infectious conditions: EUCTR retrieves trials with neonates, but not exclusively. The CTGOV expert search retrieves trials exclusively in neonates. ISRCTN retrieves a small number of studies. Thus, after loading trials with ctrLoadQueryIntoDb into a database collection, corresponding sets of trials need to be defined, based on values of fields of interest (e.g., eligibility.maximum_age from CTGOV and f115_children_211years from EUCTR), which can be obtained from the collection using dbGetFieldsIntoDf.
