[Correspondence] Oxygenation targets in acutely ill patients: still a matter of debate – Authors’ reply

For any given clinical question, well conducted systematic reviews and meta-analyses provide the best information for clinical decision making by transparently evaluating and synthesising the totality of evidence of a greater number and wider range of patients than any individual study.1 In this context, Rasmussen and colleagues and Martin and colleagues claim that the heterogeneous populations and interventions analysed in the IOTA study2 limit its generalisability and the quality of evidence. However, this logic falls short because the treatment effects were consistent across populations (eg, stroke, myocardial infarction, and critical illness), settings (eg, critical care vs no critical care), and interventions (eg, nasal prongs vs mechanical ventilation).
