Meta-analysis results: pooled AUROC for SOFA. Gray boxes represent the fixed weight estimates of the AUROC value from each study. Larger gray boxes represent larger fixed weight estimates of the AUROC values. The horizontal line through each gray box illustrates the 95% CI of the AUROC value from that study. Black horizontal lines through a gray box indicate that the CI limits exceed the length of the gray box. White horizontal lines represent CI limits that are within the length of the gray box. The vertical dashed lines in the forest plot are the estimated random pooled effect of the AUROC value from the random-effects meta-analysis. The gray diamonds illustrate the 95% CI for the random pooled effects. Tests of heterogeneity included I², τ², and Cochran Q P value (denoted as P). AUROC: area under the receiver operating curve; SOFA: Sequential Organ Failure Assessment.
