Fig. 3From: Decreased mortality in acute respiratory distress syndrome patients treated with corticosteroids: an updated meta-analysis of randomized clinical trials with trial sequential analysisTrial sequential analysis of nine trials for hospital mortality. The required information size for detecting an intervention effect was 1434 patients. The relative risk was 0.83, and the 95% confidence interval was corrected to 0.74–0.94, from 0.74 to 0.93. The cumulative Z curve crossed both the conventional boundary for benefit and the trial sequential monitoring boundary for benefitBack to article page
