When a mixed-NOCs team won a medal, the Olympic flag was raised rather than a national flag; when a mixed-NOCs team won gold, the Olympic anthem would be played instead of national anthems.

The concept of mixed-NOCs was introduced in the 2010 Summer Youth Olympics, in which athletes from different nations would compete in the same team, often representing their continent.

This is in contrast to the Mixed team (IOC code: ZZX) found at early senior Olympic Games.

If there is more than one athlete from the same nation on a medal-winning team, only one medal of that colour is credited, so therefore in this medal summary China are credited with only one gold rather than two for their participation in the gold-winning short track speed skating team.

A total of 15 National Olympic Committees, including hosts Austria, had at least one athlete representing a mixed-NOCs team win a medal.
