138 patients with conflicting results from LUS and CR were further studied with chest CT scan in all included studies. The LUS was 0.93 (0.86–0.97) sensitive and 0.72 (0.54–0.86) specific, with a pooled DOR of 24.56 (8.45 to 71.37) and an AUC of 0.901(SE, 0.036). In comparison, CR had a sensitivity of 0.54 (0.44–0.63), a specificity of 0.57 (0.39 to 0.74), a pooled DOR of 1.73 (0.42–7.10), and an AUC was 0.590(SE, 0.117), Figs 3 and 4. The Z statistic between LUS and CR of these two sROC curves was 3.093 (P = 0.002).Details of quality assessment by the QUADAS tool.
