Figure 3

Comparison of the distributions of the number of periodic limb movements per hour of sleep for the first 8 h in patients with restless legs syndrome (A) with PLMS (PLMS index > 15 events/h n = 47) and (B) without PLMS (PLMS index ≤ 15 events/h, n = 61). Values are shown as mean (columns) and standard error of the mean (whiskers). RLS, restless legs syndrome; PLMS, periodic limb movements during sleep.
