Region-wise summary of adoption of approach in current practice and preferences in future

Regions worldwide within ESTS	Adoption of VATS/RATS in current practice and future preferences
America	All have access to robot and dual console, hence major RATS performers Mexico, Argentina, Chile and Canada had limited access to robot and dual console. Hence, VATS was most adopted approach and hence preferred for future practice.
European region	Belgium, France, UK, major units of Italy and Spain, Switzerland, Bulgaria and Norway had access to robot and dual console. They were major RATS performers and preferred both VATS/RATS for future practice. Some units of Austria, Italy, Luxembourg, Hungary, Jordan and half of Switzerland centres were proponent of VATS in future. Greece had no access to robot and were adopting mixed approach but preferred both VATS and RATS in future.
Asian region	Malaysia and half of centres of Japan preferred VATS due to lack of robot. India and remaining centres of Japan, despite having access to robot, were adopting for only 10% of their anatomical resection.
Middle-East region	Only Israel had robotic access and dual console with RATS being preferred approach. Saudi Arabia had no robotic system and adopted VATS for day-to-day practice.
African region	Algeria had no robotic system and adopted thoracotomy for anatomical resection, but preferred both VATS and RATS for their future practice. Morocco had no robotic system and adopted VATS for day-to-day practice.
Australia	Out of the 2 centres, 1 of them already had an established RATS training curriculum and major RATS independent performers.
