91 (95% confidence interval [CI] 0.87-0.95; P less then 0.001) in women and 0.86 (95% CI 0.75-0.98; P less then 0.001) in men. The optimal thresholds (women 1,379 AU; men 1,802 AU) were close to those proposed in the guidelines. The diagnostic accuracy of the thresholds in the guidelines was similar to that of the optimal thresholds. Conclusions The sex-specific AVC thresholds proposed in international guidelines can be applied to Japanese AS patients, yielding similar diagnostic accuracy as the optimal cut-off derived fro
