Source notes
  • CV55 and CV58 are duplicate entries for the same publisher blog correspondence; retain one catalog item.
  • No independent DOI found for this correspondence in Crossref or primary references. Leave DOI null instead of substituting a later erratum/retraction DOI.
  • The historical publisher blog URL currently redirects to the general Medicine homepage; a successful HTTP response is not evidence that the correspondence remains accessible at that address.
  • Use the accessible publisher-notice context link as an explicitly labeled related record if the original correspondence cannot be served.
  • The exact full author names are spelled out in the related publisher retraction notice. A separate erratum cites only the first three authors, so it is not used to truncate the list.
