^aData based on study participants completing both baseline and 3 month follow-up.

^bPossible range = 1 to 10.

^cHigher score indicates greater sleep dysfunction; possible range for subscales = 0 to 3 and global dysfunction = 0 to 21. Abbreviations: M0, month 0 (baseline); M3, month 3; SD, standard deviation; d, effect size
