The impact of early postoperative pain interference on 2-year outcomes after hip arthroscopy.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe relationship between early postoperative pain and long-term outcomes after hip arthroscopy is unclear. This study examined whether 2-week postoperative pain scores are associated with 2-year patient-reported outcomes (PROs) after hip arthroscopy and compared outcomes between patients with and without early postoperative pain improvement.
methodsPatients undergoing hip arthroscopy for labral tear and/or femoroacetabular impingement syndrome were retrospectively identified from a prospectively enrolled registry. Patients completed baseline, 2-week, and 2-year surveys. Patient-reported outcomes measurement information system (PROMIS) pain interference (PI) assessed pain. Early improvement was defined as a change in PROMIS PI score relative to the minimal clinically important difference threshold of ± 3.1 points from baseline at 2 weeks postoperatively. Patient characteristics and PROs were compared between groups by early improvement status.
resultsOf 136 patients, 95 (71%) completed 2-week follow-up, and 70 of 95 (74%) completed 2-year. Improved early PROMIS PI was associated with worse baseline PROMIS Physical Function (p < .001) and PROMIS PI (p < .001), and better 2-week PROs across nearly all outcomes. Worse 2-week PROMIS PI scores correlated with worse 2-year PROMIS PI (p = .02), Fatigue (p = .02), and Anxiety (p = .002). On multivariable analysis, improved 2-week PROMIS PI was independently associated with better 2-year PROMIS PI, Marx Activity Rating Scale, and greater improvement in PROMIS PI.
conclusionEarly improvement in PROMIS PI after hip arthroscopy was independently associated with better 2-year pain and activity outcomes. Patients with improved early postoperative pain had worse baseline pain and function but better early postoperative PROs. 2-week PROMIS PI may serve as a useful prognostic indicator for 2-year PROs after hip arthroscopy.
