Fig. 2From: Diagnostic accuracy of point-of-care ultrasound for shock: a systematic review and meta-analysisSummary receiver operating characteristic curves. The summary receiver operating characteristic plots of the bivariate meta-analysis for the identification of the cause of shock by point-of-care ultrasound. The ellipse around the point estimates represents a 95% CI. The ROC curves are restricted to the range of specificities for each studyBack to article page
