Comparison of protocol-mandated cortisol levels (µg/dl) in patients with or without concerns for adrenal insufficiency.

Did patient have the following concerns for AI?	Cortisol levels (Median (IQR))
	Yes	No
1. Signs of AIa that required clinical team intervention	6.5 (3.1, 12.7) (n = 4)	9.2 (4.8, 15.3) (n = 67)
2. Clinical team restarted steroids due to signs of AI	8.7 (2.9, 14.4) (n = 2)	9.0 (4.8, 15.3) (n = 69)
3. Signs of AI based on either clinical team intervention or restarting steroids	6.5 (2.9, 14.4) (n = 6)	9.2 (4.8, 15.3) (n = 65)
	Yes	No
Failed ACTH stimulation test	10.4 (1.6, 19.2) (n = 2)	5.0 (2.8, 6.4) (n = 34)

There were no differences in levels between AI and no AI groups by Wilcoxon rank sum test.
