Note. The following data with errors were removed: children who provided their samples in the incorrect order, children who provided the 30 minute sample less than 15 minutes or more than 60 minutes after waking, children who were awake less than 12 or more than 20 hours, children who woke past noon, children for whom there was missing time of collection information, and children who provided saliva samples across different days rather than the same day. AUC = area under the curve, CAR = cortisol awakening response, DEC = daily decline.
