NHS must've got wind of the report in advance because you don't need face coverings in Ninewells any more - ended Monday past.

I saw a specialist orthopaedic surgeon early last year in Edinburgh - masks an absolute requirement in Murrayfield Hospital until you got into his office and it was 'no need for face covering in here, they do nothing - but make sure nobody sees you without one in the corridors'. Even the doctors knew the scientists were talking out their arses.
