What is the effect of pressure- and volume-limited ventilation compared to traditional mechanical ventilation with respect to survival and other outcomes in adult ALI and ARDS?

Legend*This Summary of Evidence Table corresponds to the GRADE method of summarizing clinical research evidence.§Inconsistency is described by the p-value corresponding to the Cochrane Q test for heterogeneity, the I2 statistic, and differences among study methods.¶Indirectness relates to proximity to the question of survival benefit.†The quality of randomized trial evidence can be downgraded for risk of bias, inconsistency, indirectness, imprecision, or publication bias.
