Ms Nicola Cassidy:

We wondered whether it was to do with numbers and whether critical capacity was having an influence. However, as was said, we do not have a registry so do not really know the number, but we suspect it is much more than we are estimating. I do not think it is fair to say it is a numbers game because we have potentially more than 5,000 patients diagnosed with lung fibrosis.

They cannot be excluded.
