Sleep-stage stratification pattern in CRPS for different age groups. All age groups exhibit the same stratification pattern with lowest percent synchronization during REM, higher during wake and LS, and highest during DS. This sleep-stage difference significantly decreases from a factor of 7 (comparing REM to DS) for the youngest subjects to a factor of 2 for the oldest age group. Error bars in all panels show the standard error. For different n∶m ratios see SI Text and Fig. S3.
