  1. Table 3 shows the mean differences in sleep macrostructure, respiratory (AHI, ODI) and PLM index (PLMI) between the migraine and control group, calculated with t-Test analysis.
  2. TIB time in bed, SPT sleep period time, TST total sleep time, SOL sleep onset latency, FRL first REM sleep latency, SS stage shifts, AWN awakenings, SE sleep efficiency, WASO wake time after sleep onset, S1 sleep stage 1, S2 sleep stage 2, SWS slow-wave sleep, REM rapid eye movement sleep percentage.
  3. AHI apnea/hypopnea index (normal value≤1/h), ODI oxygen desaturation index (normal value≤ 1/h), PLMI periodic limb movements index (normal value≤ 5%). NS not significant.
