^aSignificantly higher than overall store-and-forward (p = 0.002), compressed video (p = 0.003) or uncompressed video (p = 0.03), McNemar test.

^bSignificantly higher than overall store-and-forward (p = 0.004), compressed video (p = 0.02) and uncompressed video (p = .03), McNemar test.

^cSignificantly higher than overall store-and-forward (p = 0.001), compressed video (p = 0.004) and uncompressed video (p = 0.03), McNemar tests.

Differences between the remote methods were not significant (p < 0.05), Freidman test.
