Risk-of-bias assessments for individual studies investigating effectiveness according to standardized criteria for randomized studies using the Cochrane Risk-of-Bias Tool 2.0. Bias is assessed as low, high, or unsure (when sufficient information is not available to allow assessment).

Risk of bias domain	Study (Scheffer et al [27])
Random sequence generation	Low
Allocation concealment	Low
Blinding of participants or personnel	High
Blinding of outcome assessment	Unsure
Incomplete outcome data	High
Selective reporting	Low
Other bias	Unsure
Comments	High dropout, especially in the intervention group where the provided foremost reason was that the participants found the alarm too big and heavy
