Incidence of ACS development based on the serum cortisol post-DST level at diagnosis (follow-up time: 41.3 (IQR 24.7–63.1) months).

DST Group	Cases	Cumulative Incidence (95% CI)
≤0.45 µg/dL	0/5	0.00 (0.00–0.43)
0.45–0.9 µg/dL	4/83	0.05 (0.02–0.12)
0.9–1.35 µg/dL	9/117	0.08 (0.04–0.14)
1.35–1.8 µg/dL	19/100	0.19 (0.13–0.28)
Total	32/305	0.10 (0.08–0.14)

DST = dexamethasone suppression test. MH Test for linear Trend: Chi² = 10.65 (p = 0.0011).
