Check if a document exists based on its unique identier

internal

Provides functions for querying, retrieving and analysing
protocol- and results-related information on clinical trials from
two public registers, the European Union Clinical Trials Register
(EUCTR, <https://www.clinicaltrialsregister.eu/>) and
ClinicalTrials.gov (CTGOV, <https://clinicaltrials.gov/>). The
information is transformed and then stored in a database (nodbi).
Functions are provided for accessing and analysing the locally
stored information on the clinical trials, as well as for
identifying duplicate records. The package is motivated by the need
for aggregating and trend-analysing the design, conduct and outcomes
across clinical trials.
