Response from The BMJ - we've traced the authors' initial request for information

Posted by trished on 15 Jan 2014 at 14:26 GMT

We have now located the email from the authors dated August 2013
letting us know about their paper and asking us for information about
our display advertising revenue. Apologies to them for not responding
at the time.
As we have said in our earlier response, we would have
been happy to share actual figures with them, as we have done in the
past with others, had we not inadvertently overlooked the email.

Fiona Godlee and Trish Groves, The BMJ
