To the Editor: Dr Serpa Neto and colleagues1 addressed the issue of whether the use of protective ventilation would be associated with a benefit in patients without acute respiratory distress syndrome (ARDS). However, this review was not without limitations, including the phenomenon in meta-analyses termed small study effects. Small study effects refer to the fact that small trials are more likely to report beneficial effects in the intervention group.2
