6MWT and SMARTREAB telemonitoring compared.

6MWT SMARTREAB Difference of means* 95% CI P-value**
Nadir SpO2 (%; mean ± SD) 86.2 ± 6.2 79.0 ± 8.2 7.2 ± 8.4 5.6 to 8.9  < 0.0005
Peak HR (%; mean ± SD) 71.2 ± 11.9 80.6 ± 11.2 − 9.3 ± 15.5 − 12.4 to − 6.2  < 0.0005
Activity intensity (MET; mean ± SD) 2.6 ± 0.5 2.9 ± 0.7 − 0.3 ± 0.8 − 0.5 to − 0.2  < 0.0005

*Calculated pairwise.

**Paired sample t-test.

Nadir SpO2: lowest peripheral oxygen saturation detected; HR: heart rate; MET: metabolic equivalent of task; 6MWT: six-minute walk test; CI: confidence interval; SD: standard deviation.
