Figure 2From: Effects of steroids on reintubation and post-extubation stridor in adults: meta-analysis of randomised controlled trialsRisk of reintubation according to the studied population. Risk ratio of reintubation rate for the individual randomised controlled trials comparing steroids with control groups. Vertical line = 'no difference' point between the two groups; squares = risk ratios (the size of each square denotes the proportion of information given by each trial); diamonds = pooled risk ratios for randomised controlled trials that did not select patients at high risk (upper) and trials that did select patients at high risk, based on a reduced cuff-leak volume (CLV; lower); horizontal lines = 95% confidence intervals (CI).Back to article page
