Proposed follow-up for NFAIs based on serum cortisol post-DST levels at diagnosis.

DST Value at Diagnosis	Risk of ACS in Five Years	Suggested Follow-Up Recommendation
<0.9 µg/dL	5.8%	DST 5 years after diagnosis *
0.9–1.45 µg/dL	7.1%	DST every 2.5 years after diagnosis for 5 years *
1.45–1.8 µg/dL	19.8%	DST yearly after diagnosis for 5 years *

* Consider measuring ACTH, UFC and/or DHEAS depending on their values at diagnosis. Risk refers to the follow-up period of this study (41.3 (IQR 24.7–63.1) months).
