*The example is an expert search that retrieves interventional trials with neonates, investigating infectious conditions: The CTGOV expert search retrieves trials conducted exclusively with neonates. It is not yet clear why different sets of trials are shown in CTGOV (65) and CTGOV2 (14) for the same query parameters. EUCTR retrieves trials with neonates, but not only those exclusively in neonates. ISRCTN retrieves studies with interventions other than medicines. Thus, after loading trials with ctrLoadQueryIntoDb into a database collection, trials of interest have to be selected in a second step, based on values of fields of interest (e.g., using f115_children_211years from EUCTR for age criteria, interventions.intervention.interventionType from ISRCTN for type of study), which can be obtained from the collection using dbGetFieldsIntoDf.
