Dr. Goldacre:

Thank you so much for bringing this error to our attention. You are absolutely correct in your research to assess the correct National Clinical Trial number for our research.

The proper number is NCT00332722.

We have immediately corrected the open access version of this manuscript available online. The pdf available on the Pain Physician site now reflects the correct Clinical Trial numbers. We are also checking all our manuscript for potential errors.

We will run an erratum in the next issue of Pain Physician journal and will also ask that the error be corrected on PubMed.

Again, we appreciate your taking the time to point out this error to us.

This trial has the wrong trial registry ID associated with it on PubMed: both in the XML on PubMed, and in the originating journal article. The ID given is NCT0033272. We believe the correct ID, which we have found by hand searching, is NCT00332722.

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; we hope that this trial’s text and metadata can also be corrected at source, in PubMed and in the accompanying paper.

Many thanks,

Jessica Fleminger, Ben Goldacre*
