Systemic rates of appearance of C13 cortisol (derived from ingested ¹³C cortisone) (A) calculated using Steele's steady-state equation in hydrocortisone (white rectangles) and placebo (black triangles) groups following the ingestion of 1.0 mg of ¹³C cortisone at time 0. *P = .02 vs placebo group. Hepatic C13 cortisol production (B) in hydrocortisone (shaded bars) and placebo (white bars) groups over 240 minutes following the ingestion of 1.0 mg of ¹³C cortisone at time 0. *P = .02 vs placebo group.
