Design outcomes

Primary

Measure	Time frame
Postoperative pain at rest was the primary outcome measure which was assessed using the visual analog scale (VAS) (scale 0–10, where 0 = no pain and 10 = worst imaginable pain). Pain assessment by VAS score was explained to all the patients before surgery and taught the VAS score for self-assessment of pain at the time of enrollment for the study and to the nurse staff attending the patients. Post operative pain at rest was assessed by VAS score of scale from 0-10 and was recorded at 24 h after surgery.	—
