Results of the dexamethasone suppression test (DST) and the cortisol
suppression index (CSI) were compared in 50 depressed prepubertal children
and 36 control subjects. The 4:00 p.m. DST, the two-point DST, and the 8:00
a.m. revised criterion CSI yielded the best results and had similar
clinical utility and diagnostic confidence values.
