rial oxygen (PaO2)/inspired fraction of oxygen (FiO2) \100 mmHg] compared with moderate hypoxemia (100 mmHg B PaO2/
FiO2 B 300 mmHg). Design:Systematic review and meta-analysis. Data Sources: Electronic databases (to November 2009) and conference proceedings. Methods: Two authors independently selected and extracted data from parallel-group randomized controlled trials comparing prone with supine ventilation in mechanically ventilated adults or children with AHRF. Trialists provided subgroup data. The primary outcome was hospital mortalityin patients with AHRF and PaO2/FiO2 \100 mmHg. Meta-analyses used study-level random-effects models. Results: Ten trials (N = 1,867 patients) met inclusion criteria; most patients had acute lung injury. Methodological quality was relatively high. Prone ventilation reduced mortality in
patients with PaO2/ FiO2 \100 mmHg [risk ratio (RR) 0.84, 95% conﬁdence interval (CI) 0.74–0.96; p = 0.01;...
