Demographic and medical information
In total, 69 (75%) children consented to the study; details of participant enrollment are described in Figure 1. There were no differences in age and sex between participants and nonparticipants, however, nonparticipants more often had cerebral tumors compared to participants (Table 1). There were no differences in age, sex, and tumor location between participants and patients who were not approached.
The baseline characteristics of the participants are described in Table 1. Of the children with supratentorial midline tumors (N=26, 38%), fifteen children (22%) had a tumor in the pituitary region, and no child had a tumor in the hypothalamus. In the whole participant group, pre-existing sleep problems were reported by the parents of seven (10%) participants, six (9%) participants took daytime naps and two (3%) participants used melatonin during the assessment. No nights were spent in the hospital during sleep examination.
