The comparison of recurrence rates in patients who slept in different positions during the 2–4 weeks after the repositioning maneuver (excluding the recurrent patients in one week after repositioning maneuver).

–4 weeks after the repositioning maneuver (P>0.05, Fisher's exact test). The patients who took a random sleep position had a lower recurrence rate than patients sleeping in other positions (P<0.05, Fisher's exact test). The patients sleeping on their affected side did not have a higher recurrence rate than patients sleeping in other positions during the 2
