  1. *The risk in the intervention group (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI)
  2. CI Confidence interval, COPD Chronic obstructive pulmonary disease, ER Emergency room, RCT Randomized clinical trial, RHM Remote home monitoring
  3. a Study(ies) at high risk of bias
  4. b Small sample size
  5. c Study at high risk of selection bias and presence of confounding variables
  6. d The outcome is an indirect measure of compliance with intervention
