Fig. 2 — Primary outcomes in patients admitted with acute onset dyspnea when PoCUS was used compared to conventional modalities (control). Comparison of patients admitted with dyspnea examined by PoCUS vs conventional modalities in time to diagnosis (considerable heterogeneity detected) (A), time to treatment (considerable heterogeneity detected) (B), and length of stay in the Intensive Care Unit (moderate heterogeneity detected) (C). PoCUS indicates Point of Care Ultrasound; SD, standard deviation; MD, mean difference. The size of squares is proportional to the weight of each study.
