NICE's clinical and public health director Professor Peter Littlejohns said: 'In order for our guideline development groups to carry out their job effectively we need to have access to all available data. However, we cannot force organisations or companies to submit unpublished data.'
Health minister Ivan Lewis has backed the call for firms to publish all data. ‘'I would call on any company in possession of any relevant evidence to make it available to NICE,' he told the Observer.
He said firms that failed to do so would give the impression they had 'something to hide'.
