Those in remission had higher ACTH variability at AM (P = .02) and PM (P &amp;lt; .001) time points compared to nonremission. The nonremission group had a significantly narrower diurnal range compared to the remission group (P = &amp;lt;.0001). A decrease in plasma ACTH of \u226550% from mean preoperative levels predicted CD remission after TSS, especially when using PM values. The absolute plasma ACTH concentration and ratio of preoperative to postoperative values were significantly associated with nonremission after multivariable logistic regression (adj P &amp;lt; .001 and .001, respectively).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Our findings suggest that ACTH variability is suppressed in CD, and remission from CD is associated with the restoration of this variability. Furthermore, a decrease in plasma ACTH by 50% or more may serve as a predictor of remission post-TSS. These insights could guide clinicians in developing rational outcome measures for interventions targeting CD adenomas.<\/jats:p>\n
