Mortality (critical outcome) | Not reported |
Downgraded by 1 increment if the majority of the evidence was at high risk of bias and downgraded by 2 increments if the majority of the evidence was at very high risk of bias
Downgraded by one increment if the confidence interval crossed one MID and downgraded by two increments if the confidence interval crossed both MIDs. MID for machine usage (adherence)- 1 hour; Established MIDs for SF-36 physical/mental- 2/3 ; FOSQ- 2 ; ESS −2.5;SAQLI – 2. GRADE default MID (0.5XSD) used for all other continuous outcomes.
Downgraded by 1 or 2 increments for heterogeneity,unexplained by subgroup analysis. Random effect analysis used.
Downgraded by 1 or 2 increments because the majority of the evidence included an indirect or very indirect population respectively
Not sleepy in both groups
