Difference between centre-based and home or remote test administration.

Test	Study	Comparison	Difference
6MWT	Holland et al. 20158	Centre vs home	6MWD mean 30.4 metres longer at the centre (95%CI 0.4 to 63.2 metres)
	Brooks et al. 20037	Indoor vs outdoors	6MWD mean (SD) 394 (86) vs 398 (84) metres, p = 0.4
	Juen et al. 20149	App vs in person	6MWD MD 0.3 m (95%CI – 73 to 72 metres) App absolute error for 6MWD 5.87%
	Juen et al. 201510	App vs in person	App error for 6MWD 3.78%
3MST	Cox et al. 201359	Remote supervision vs in person	Nadir SpO2 MD 0.2% (LOA – 3.4 to 3.6%) Rate of perceived exertion MD 0.5 points (LOA – 1.1 to 2.1 points) Pulse rate MD - 0.6 beats/min (LOA – 11.3 to 10.1 beats/min).

3MST – 3-minute step test, 6MWD – 6-minute walk distance, 6MWT – 6-minute walk test, 95%CI – confidence interval, LOA – limits of agreement, MD – mean difference, SD – standard deviation, SpO₂ – oxyhaemoglobin saturation.
