Fig. 3From: Unmatched ventilation and perfusion measured by electrical impedance tomography predicts the outcome of ARDSPercentage of unmatched units and clinical outcome. a Unmatched units in survivors versus non-survivors. For each boxplot, the line within the box indicate the median value, the box boundaries indicate 25th and 75th percentiles, and the error bars indicate the 5th and 95th percentiles. P-values for Wilcoxon-signed rank test. b ROC curve for SAPS II and unmatched units. c Correlation between unmatched units and ventilator-free daysBack to article page
