We thank Dr. Byrne for their comment on our article.1 The periodic limb movement (PLM) Index in the APPLES study was scored based on the AASM scoring manual, which defines the leg movements—LMs, as appropriately pointed by the commenter—and the periodicity—the minimum number of consecutive LM events needed to define a PLM series (4 LMs) plus the period length between LMs (5–90 seconds). The APPLES database provides a variable “PLM criteria index”—defined as above—which the authors can confirm was used for the current manuscript. The authors are not aware of a separate limb movement index (LMI) scored in APPLES study.
