Methods | Prospective, single‐centre RCT | |
Participants | n = 38. ARDS | |
Interventions | Treatment: RM (PEEP 40 cm H2O, support pressure set to 0, FiO2 1.0 for 30 seconds), repeated 8‐hourly for 5 days Both groups: PSV, Pplat ≤ 30 cm H2O, minimum PEEP with FiO2 < 0.6 and PaO2 60‐80 mmHg |
|
Outcomes | Oxygenation status for 5 days, lung injury indexes, adverse effects of RM and incidence of barotrauma | |

Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Low risk | Envelope method |
Allocation concealment (selection bias) | Low risk | "The envelope method" |
Blinding (performance bias and detection bias) All outcomes | Unclear risk | Not stated |
Incomplete outcome data (attrition bias) All outcomes | Unclear risk | Information was insufficient to permit a judgement. |
Selective reporting (reporting bias) | Unclear risk | Information was insufficient to permit a judgement. |
Intention to treat | Unclear risk | Information was insufficient to permit a judgement. |
