Fig. 6From: Value of respiratory variation of aortic peak velocity in predicting children receiving mechanical ventilation: a systematic review and meta-analysisSummary receiver operating characteristics curve of respiratory variation of aortic peak velocity for the prediction of fluid responsiveness in a mean age of ventilated children < 25 months and b mean age of ventilated children ≥ 25 months. Circles represent each study included in the meta-analysis. AUC, area under the curve; SENS, sensitivity; SPEC, specificity; SROC, summary receiver operating characteristicsBack to article page
