ctrdata 1.19.2
Improvements
- Added typing for newly appearing variables in
CTIS
- Accelerated
CTIS
trial data processing
Bug fixes
- Fix incomplete downloads from
CTIS
by disabling HTTP/2
multiplexing in another function
ctrdata 1.19.1
Improvements
- Revised translation of location elements from search URL to API call
for
CTGOV2
ctrdata 1.19.0
Possibly breaking changes
CTGOV
has retired on 2024-06-25 the classic website
and API used by ctrdata
since 2015. To support users,
ctrdata
now automatically translates and redirects queries
to the current website. This helps with automatically updating
previously loaded queries
(ctrLoadQueryIntoDb(querytoupdate = <n>)
), manually
migrating queries and reproducible work on clinical trials information.
This new functionality in ctrdata
translates a user’s
search query URL from the classic website into a query for the current
CTGOV
website, for all search parameters. Since the
structure and format of data differs between data retrieved from the
current API and previously retrieved from the classic API,
ctrdata
will continue to identify the current API as
register = "CTGOV2"
, to support the analysis stage. In
addition, ctrdata
documentation continues to include
examples of analyses with CTGOV
data, as this may have been
downloaded earlier.
CTIS
has been relaunched on 2024-06-17, and
ctrdata
has been fully updated to it. At the moment,
CTIS
provides basic searches and no search query URL. To
support users, ctrdata
includes an updated script that
extracts a user’s search parameters from the register search page to the
clipboard and into the browser URL bar. In addition, the script triggers
a search for trials when opening such a query URL, see
https://rfhb.github.io/ctrdata/#id_2-script-to-automatically-copy-users-query-from-web-browser.
File names of CTIS
documents start now with the document
type,
e.g. SbjctInfaICF - L1 SIS and ICF NL for publication.pdf
,
since the prefix (document source) introduced in version 1.18.0 is no
more applicable.
Improvements
- Reduced size of demo database in package, addressing
CRAN
notes
- Adapted
ctrFindActiveSubstanceSynonyms()
to
CTGOV2
API; this is now based on terms used in studies
- Updated vignette and added inspecting a specific trial
- Updated register information, adding caveats and issues
- Updated estimated download sizes and user information
- Avoided duplicate data and file retrievals
- New attribute
ctrdata-collection
for data frames with
trial information; same content as attribute ctrdata-table
,
which will be removed by end 2024
- Split utils.R into files for functions and fields
Bug fixes
- Correct partial date brackets for
CTGOV2
- Disable HTTP/2 multiplexing for
CTIS
ctrdata 1.18.0 (2024-05-13)
Possibly breaking change
- File names for documents downloaded from
CTIS
now
include the document type and use different separators (e.g.,
“parts2auth - SbjctInfaICF - …” as abbreviation of “Subject information
and informed consent form (for publication)”, was previously
“parts2auth_…”)
Improvements
- Add retrieval of historic versions of trial records from
CTGOV2
(automatically retrieved from CTIS
, not
available for other registers)
- Added typing of newly appearing fields from
CTIS
- Increase testing coverage to 93.7% locally
- Added missing CI for the combination of
DuckDB
and
CTGOV2
Bug fixes
- Correct typing certain fields as (lists of) integers
- Handle marginal case in
dbGetFieldsIntoDf()
- Changed
unlink
of intermediate files
- Minor vignettes corrections
ctrdata 1.17.2 (2024-02-25)
Bug fixes
- Switch sequence of API endpoints used with
CTIS
- Correct handling multiple public events with
CTIS
- Re-use
CTIS
downloads in a given session
ctrdata 1.17.1 (2024-02-05)
Improvements
- Additional
CTIS
field types and possibly documents
(associated clinical trials)
- Use
ctId
instead of id
as
CTIS
top-level field (a further synonym used in the API is
clinicalTrialId
)
Bug fixes
- Added handling of unexpected Unicode in protocol-related data from
one trial in
EUCTR
- Improved predicted download sizes and times for
EUCTR
- Return with message if
CTIS
query did not result in any
trials
ctrdata 1.17.0 (2024-01-22)
Possibly breaking changes
- Reimplemented
dbGetFieldsIntoDf()
to accelerate and
have more predictable, simplified returns, in particular for nested
fields; also attempts to recursively expand simply nested data into
additional columns in the returned data frame
- Reimplemented
dbFindFields()
to accelerate; both based
on improved nodbi::docdb_query()
dbFindFields()
now digests a sample of records to
quickly find fields, or all records if sample = FALSE
but
taking increasing time with increasing number of records
- If using
nodbi::scr_postgres()
, parameter
fields
of dbGetFieldsIntoDf()
is limited to
less than 50 fields; a message flags for any backend potential
compatibility issues, suggesting to use parent fields, e.g.,
a.b
instead of c("a.b.c.d", "a.b.c.e")
- Parameter
stopifnodata
of
dbGetFieldsIntoDf()
is no more needed and deprecated
- Reimplemented typing fields to speed up and to simplify
Improvements
- Register data are re-used and not downloaded again in an interactive
session (that is, the same temporary folder is now re-used throughout a
user’s session)
- Temporary folder can be set by users with
options(ctrdata.tempdir = "<user_specified_folder>")
- Inform MS Windows users if
cygwin
was found so that
they may chose to delete it
- Many fields added for typing e.g. as date in
dbGetFieldsIntoDf()
Bug fixes
- Adapted and corrected information loading to newly available data in
CTIS
- Corrected escaping, and back-conversion, of characters in
JSON
from CTIS
ctrdata 1.16.0 (2023-11-24)
Possibly breaking changes
XML files are
converted slightly differently
- EUCTR result-related information in attributes: e.g. new:
{"id":"PostAssignmentPeriod-46349"}
, was:
{"@attributes":{"id":"PostAssignmentPeriod-46349"}}
- Consequently, it should work to just delete
@attributes
from field names such as
dbGetFieldsIntoDf("clinical_results.baseline.analyzed_list.analyzed.count_list.count.@attributes.value", db)
- EUCTR protocol-related information although no differences were
found yet
- CTGOV attributes of bare values remain not included in the resulting
NDJSON
(e.g., some but not all records have
<start_date type="Actual">March 15, 2004</start_date>
,
and this is converted to
{"start_date":"March 15, 2004"}
)
EUCTR:
some renaming to harmonise EU and 3rd country trial fields
- new:
e83_single_site_trial
, was (EU trials):
e83_the_trial_involves_single_site_in_the_member_state_concerned
- new:
e83_single_site_trial
, was (3rd country trials):
e83_will_this_trial_be_conducted_ at_a_single_site_globally
- new:
e863_trial_sites_planned_in
, was (EU trials):
e863_specify_the_regions_in_which_trial_sites_are_planned
- new:
e863_trial_sites_planned_in
, was (3rd country
trials):
e863_specify_the_countries_outside_of_the_eea_in_which_trial_sites_are_planned
- new:
e84_multiple_sites_in_member_state
, was (EU
trials):
e84_the_trial_involves_multiple_sites_in_the_member_state_concerned
- new:
e840_multiple_sites_globally
, was (3rd country
trials):
e84_will_this_trial_be_conducted_at_multiple_sites_globally

https://github.com/rfhb/ctrdata/issues/26#issuecomment-1749555081
Bug fixes
- corrected batch iterations over CTIS trials accommodating unclear
totalSize
response
- corrected translation of some fields from the browser URL to the API
call for CTGOV2 (closes https://github.com/rfhb/ctrdata/issues/32)
- corrected minimum curl version to 5.1.0 (closes
https://github.com/rfhb/ctrdata/issues/31)
- handled errors when saving EUCTR results (e.g., too long file path
name, closes https://github.com/rfhb/ctrdata/issues/30 and
https://github.com/rfhb/ctrdata/issues/28)
Improvements
Major
- No external tools required any more
(
Cygwin
, perl
, cat
,
sed
, php
functionality for transforming text,
XML and NDJSON replaced by Javascript using R
package
V8
); addresses personally communicated concerns and
faciliates use of package ctrdata
in more environments
(e.g., https://github.com/rfhb/ctrdata/issues/26); consequently, this
might be a breaking change for analysing certain fields, see above which
fields are affected.
