Fig. 3: Meta-analysis of diagnostic accuracy of POCUS for confirmation.

A Sensitivity of POCUS across included studies with pooled estimate and heterogeneity statistics. B Specificity of POCUS with pooled estimate and heterogeneity statistics. C Positive likelihood ratio (+LR) with pooled estimate. D Negative likelihood ratio (–LR) with pooled estimate. Squares represent study-specific estimates, horizontal lines indicate 95% CIs, and diamonds show pooled effects.
