Independent observers, blinded to each other's assessments, evaluated hepatic steatosis visually and through USAT measurements. Separate measurements were taken at five intercostal and subcostal sites, and the median values of these measurements were recorded. The correlation between USAT measurements and visual steatosis grades was examined using Spearman's correlation test. Intraclass correlation coefficient (ICC) and Bland\u2013Altman analysis were used to evaluate the interobserver variability of USAT measurements.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Interobserver agreement for USAT measurements was excellent for the intercostal examination and good for the subcostal examination (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). Body mass index did not significantly affect the level of interobserver agreement. Interobserver variability in Bland\u2013Altman plots of USAT measurements was within the 95% limits of agreement. USAT measurements correlated very strongly with the visual degree of hepatic steatosis, both intercostal and subcostal (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001).
