The mean IAS\u2010AT volume was 1.8\u2009\u00b1\u20091.5\u2009mL, and attenuation was \u221269.3\u2009\u00b1\u20098.9 HU.

Receiver operating characteristic analyses revealed that the predictive value of IAS\u2010AT attenuation was comparable to that of LA\u2010EAT attenuation other than IAS\u2010AT (area under the curve (AUC), 0.611 vs. 0.602;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.815).
