Clinical trial protocols and published trials

The Trials part of the Cochrane Library, also referred to as CENTRAL, contains published trials and published protocols, but also trial protocols from a number of trials registries including ClinicalTrials.gov.For those, the Trials (CENTRAL) record does not seem to record publications.   Of course, an ongoing trial won ' t have any, but some records record the existence of results, if not details of  where they were published.Records from ClinicalTrials.gov are linked from CENTRAL.  Those ClinicalTrials.gov records do have a space for publications from the trial, but that may not always be filled in even if there are publications.As an example, two COVID trials:https://clinicaltrials.gov/study/NCT04523571andhttps://clinicaltrials.gov/study/NCT04368728Neither of these record any publications from the trial (I imagine it is down to the investigators, or whoever registered the trial, to provide that information).   The ClinicalTrials.gov ID is included in PubMed as part of the SI field, so is searchable, and searching for those same two trials: NCT04523571[si]andNCT04368728[si]finds publications for both.  Some for NCT04368728 may be about the trial, rather than trial results, but some are definitely results.If there are no publications of results recorded in ClinicalTrials.gov, and searching the NCT number finds nothing, then perhaps other possibilities are:Searching PubMed for an investigator and some words from the protoc...
