SECONDARY outcome

Timeframe: Participants will be followed for the duration of their hospital stay, an expected average of 2.5 days.

VAS was measured using a scale that ranged from 0 to 10. Higher scores indicate more pain, or a worse outcome. Patients had pain measured a variable number of times following surgery before discharge. Mean VAS score during the hospital stay for each patient was calculated
