Correction to: Low concordance between CTPA and echocardiography in identification of right ventricular strain in PERT patients with acute pulmonary embolism (Emergency Radiology, (2023), 30, 3, (325-331), 10.1007/s10140-023-02130-z)

After publication of the paper, the authors discovered an error in the statistical code that affected the published results. We have now corrected this code and updated the results in the manuscript accordingly. The corrections changed the results of the paper generally and most notably, increased the specificity of CTPA. The corrections as follows: In the article title, Low concordance should only be Concordance. In the abstract section, updated that 395 (71%) had concordant RVS findings on CTPA and TTE, and that CTPA had sensitivity of 69% (95% CI 64-74%) and a specificity of 74% (95% CI 68-80%). In the body of text, updated numbers, so that that 288 patients (52%) had RVS on CTPA, but only 333 patients (60%) had RVS on TTE. Concordant results of RVS occurred in 395 (71%) patients and discordant results occurred in 159 (29%). Same sensitivity and specificity as in abstract, and positive predictive value (PPV) of 80% (95% CI 76-85%) and a negative predictive value (NPV) of 62% (95% CI 56-68%). We changed the text to state that compared to TTE, CTPA was moderately sensitive and specific for RVS identification. A limitation based on original numbers was removed. The conclusion now states that compared to TTE, CTPA had moderate sensitivity and specificity, and that we suggest that RVS on CTPA should not stand alone to support a decision to pursue advanced therapy In Figure 2, numbers have been updated and corresponds to the text. Figure 2 has been replaced. Lastly, Table 2: numbers, sensitivity, specificity, PPV and NPV have been corrected. In the article title, Low concordance should only be Concordance.
