Polysomnographically Defined Restless Sleep Disorder and Periodic Limb Movements during Sleep in Children Born Prematurely

The PLMS index was positively correlated with gestational age at birth (with a small-to-medium correlation coefficient), although this did not reach statistical significance; however, it was negatively correlated with sleep efficiency (with a similar medium-size correlation coefficient, although not significant) and negatively correlated with oAHI (with a medium-to-large and significant correlation coefficient).
