This trial has the wrong trial registry ID associated with it on PubMed. The ID given is NCT0019256. The correct ID is NCT00192556. This has been corrected in a subsequent correction published in the originating journal, but not in the PubMed metadata.

This comment is being posted as part of the OpenTrials.net project^[1] , an open database threading together all publicly accessible documents and data on each trial, globally. In the course of creating the database, and matching documents and data sources about trials from different locations, we have identified various anomalies in datasets such as PubMed, and in published papers. Alongside documenting the prevalence of problems, we are also attempting to correct these errors and anomalies wherever possible, by feeding back to the originators. We have corrected this data in the OpenTrials.net database and this ID has already been corrected in the originating journal; we hope that this trial’s text and metadata can also be corrected in PubMed.

Many thanks,

Jessica Fleminger, Ben Goldacre*
