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.
