  1. TST total sleep time, SOL sleep onset latency, AHI apnea hypopnea index, PSQI Pittsburgh Sleep Quality Index, OSA obstructive sleep apnea, PLMD periodic limb movement disorders, RBD rapid eye movement sleep behavior disorders, RLS restless legs syndrome, PLMI periodic leg movement during sleep index.
  2. aOSA is defined by an AHI of ≧ 5 events/h. PLMD is defined by PLMI ≧ 15.
  3. bThe percentages in the table reflect the prevalence of each drug category among the study participants. It is important to note that the totals exceed 100% as individuals were prescribed medication from multiple categories.
