Data are presented as mean ± SD. The Mann-Whitney test was used to determine the P values. The percentages of wakefulness after sleep onset (WASO) and sleep stages are referred to sleep period time (SPT).
RLS refers to restless legs syndrome; PLMS, periodic leg movements of sleep; TIB, time in bed; TST, total sleep time; REM, rapid eye movement; SWS, slow wave sleep
Significant after Bonferroni correction.
