Outcomes
Primary Outcome Measures
the incidence of POST scores > 3
POST was evaluated by the Numerical Rating Scale (NRS), which ranges from 0 to 10 points, with 0 indicating completely painless, 1~ 3 indicating mild discomfort, 4 ~ 6 indicating moderate pain, and 7~ 10 indicating severe pain.
Secondary Outcome Measures
the POST scores
POST was evaluated by the Numerical Rating Scale (NRS), which ranges from 0 to 10 points, with 0 indicating completely painless, 1~ 3 indicating mild discomfort, 4 ~ 6 indicating moderate pain, and 7~ 10 indicating severe pain.
