Serum morning cortisol levels in paediatric IBD patients at the end of oral prednisolone therapy. The 59 patients are divided into groups according to their present glucocorticoid dose. Bars represent the range of the cortisol level; horizontal lines the median cortisol level. The percentages above the bars describe how many percent of the patients had normal serum cortisol level. The horizontal dashed line at 69 nmol/l is the lower limit for normal serum morning cortisol level. In the first group receiving * <5 mg defines group of patients receiving 5 mg prednisolone on alternate days N = 20, in the second group receiving 5 mg a day N = 18, and in the third group receiving 10 mg a day N = 21.
