Feature request: Include other trial data fields from Eu clinical trials register #10

Closed rodgersk410 closed 6 years ago

Hi, would it also be possible to include the following fields for analysis?

Start Date image

Results version number, First version publication date, This version publication date, Other versions, Summary report(s) (Yes/No) image

Hi, thanks.

(1) When hovering over the "Start Date", the pop up reads for EEA CTAs, "Date study was authorised to proceed". Such a "Start Date" can be calculated, for example like here for EEA CTAs: https://github.com/rfhb/ctrdata/blob/master/vignettes/ctrdata_usage_examples.Rmd#find-trial-start-date (example could be extended for "Outside EU/EEA" trials). Therefore, this feature seems already available.

(2) The feature request is for information (Results version number, This version publication date, First version publication date, Other versions, Summary report) which would require an additional way of downloading information from the register. What would be the use case for which this information is required? Thanks.

For (1), it looks like the Start Date displayed is actually based on the "Date of Competent Authority Decision" of the earliest started CTA. So it can be calculated. Thanks.

I'm interested in analyzing whether trial results have been posted on time per https://ec.europa.eu/health/sites/health/files/files/eudralex/vol-10/2012_302-03/2012_302-03_en.pdf

New feature to address (2) is now implemented in version 0.11: From EUCTR, fields "firstreceived_results_date" (a date) and "version_results_history" (text) are now retrieved when calling ctrLoadQueryIntoDb(query, euctrresults = TRUE). Thanks for the suggestion concerning timely posting of clinical trial results.
