Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | PPSP prevalence in relation to baseline TMT B minus A time | Six months | The time to complete TMT B test minus the time to complete TMT A test (B-A) at baseline between patients with persistent post surgical pain at six months follow-up, compared to patients without persistent post surgical pain. | ClinicalTrials.gov |
| Primary | PPSP prevalence in relation to baseline Stroop interference effect test score | Six months | The Stroop interference effect time (time to complete mixed color wording - time to complete same color wording) at baseline between patients with persistent post surgical pain at six months follow-up, compared to patients without persistent post surgical pain. | ClinicalTrials.gov |
| Secondary | Comparison of cognitive test scores and severity of PPSP between patients undergoing total knee arthroplasty vs. patients undergoing thoracotomy/mastectomy | up to one year | Association between baseline TMT B score and Stroop color interference effect results and severity of PPSP at six months follow-up in patients undergoing total knee arthroplasty vs. patients undergoing thoracotomy/mastectomy | ClinicalTrials.gov |
| Secondary | Multiple regression analysis | up to one year | Association of the following risk factors with PPSP at six months: cognitive flexibility (TMT and CWMST), age, gender, BMI, type of surgery, use of regional anesthesia, presence of preoperative pain, preoperative anxiety or depression, presence of prior stressful life events, and presence of severe acute postoperative pain) | ClinicalTrials.gov |
