Figure 1

Distribution of leg movement activity (LMA) ± 30 s around the beginning, middle, and end of respiratory events. The distribution of LMA was constructed based on the information (in ms) about the onset and duration of LMs that occurred within the depicted interval (for details see Methods). Upper panel: Distribution of respiratory-related LMA according to the WASM/IRLSSG criteria, which consider only the interval ± 0.5 s around the end of the respiratory event. Middle panel: respiratory-related LMA according to the AASM criteria, which consider an interval of −0.5 s before the beginning to +0.5 s after the end of respiratory events. Lower panel: All LMA observed around the beginning, middle, and end of respiratory events.
