Patients
We retrospectively considered all patients who underwent poly(somno)graphic evaluation at the Sleep Medicine and Long-Term Ventilation Unit of the Bambino Gesù Children’s Hospital in Rome from January 2012 to December 2022.
The following poly(somno)graphic indices were considered:
Mixed and obstructive apnea-hypopnea index (MOAHI): defined as the number of mixed or obstructive apneas and hypopneas per hour of total sleep time (TST);
Central apnea index (cAHI): defined as the number of central apneas per hour of TST.
Patients having a cAHI ≥ 1 event/hour have been enrolled for this study. Furthermore, for each patient, the following additional items were assessed:
Considering the retrospective nature of the analysis, the current study did not require the approval of the competent Ethic Committee, according to current legislation, but a notification was sent. Data were processed and retrospectively analyzed in compliance with the provisions of the GDPR and with the related national legislative and regulatory provisions in force, including any subsequent amendments and/or additions thereto.
