  1. A: Demographic data are based on available clinical reports. Age is at time of electrode implantation, and was not available for all patients. Age is listed as mean plus or minus the standard deviation, with the minimum and maximum values listed in parentheses
  2. B: The patient ILAE outcome class from each center shows that the Mayo cohort had many patients with poor outcome, so it is difficult to compare HFO results between the two centers
  3. C: The number of detected HFOs from each center using each of the three detection schemes is shown. Data from UM include all NREM sleep during the whole hospitalization, and from Mayo are continuous data from 1–3 AM
