*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.
