Data sources and searches:
We looked at all published and unpublished RCTs of Cryoablation being
used as a first line therapy to treat atrial fibrillation. We consulted
the head of Saab Medical Library, Dr. Ola El Zein to create a
comprehensive search strategy. We applied the search strategy and
modified it to fit different official and grey literature databases, as
well as RCT registers.
