| General quality criteria |
|
|
| Sample size (total number of participants) |
| Randomization allocation concealment (adequate, inadequate or uncertain) |
| Objective selection criteria for participants: |
| Yes: if inclusion and exclusion criteria for participants are adequately reported |
| No: if selection criteria are not reported |
| Blinding: |
| Yes: for articles that implemented blinding at any level |
| No: for articles reporting not being able to implement blinding of interventions at any level |
| Not reported: for articles that did not make any mention of blinding |
| Standardization of co-interventions: |

| No: if no attempt to standardize was applied |
| Uncertain: if this was not clearly reported |
| Intention-to-treat analysis (adequate, inadequate or uncertain) |
| Complete follow-up details (yes, no, not reported) |
| Outcome definition: |
| Adequate: if objective criteria for endotracheal intubation were defined |
| Inadequate: if the criteria were not defined |
| Uncertain: if application of criteria was unclear |
| Specific quality criteria |
| Patient selection criteria (inclusion and exclusion) |
| Type of patients (presence of baseline co-morbidity: AMI or chronic obstructive pulmonary disease) |
| Description of baseline criteria for severity of illness |
