The trajectory of patient-reported outcomes after hip preservation surgery: A National Registry Study.

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
purposeUnderstanding the trajectory of postoperative patient-reported outcomes after hip preservation surgery is essential. This study aims to analyse patient-reported outcome trajectories up to 2 years post-surgery using the UK's national hip preservation registry and to examine the influence of potential confounders.
methodsPatients who underwent hip arthroscopy or periacetabular osteotomy with preoperative International Hip Outcome Tool-12 (iHOT-12) scores and at least two follow-up measurements at 6 months, 1 year, or 2 years were included from the UK Non-Arthroplasty Hip Registry. iHOT-12 score trajectories were analysed, and Latent Growth Curve Modelling was used to identify predictors of these trajectories.
resultsOverall 9845 patients were included in this study. 7081 patients underwent a hip arthroscopy, and 1327 patients underwent a periacetabular osteotomy. For hip arthroscopy, there were significant improvements in the iHOT-12 scores from baseline to 6 months, but no significant change from 6 months to 1 year. However, there was a decrease in the minimal clinically important difference from 1 to 2 year. For periacetabular osteotomy, there were significant improvements in the iHOT-12 scores from baseline to 6 months, but no significant change from 6 months to 1 year, and from 1 to 2 years. Latent Growth Curve Modelling showed that body mass index (BMI) and sex had a significant impact on pre-operative iHOT-12 scores, while age and sex significantly influenced the recovery slope.
conclusionsPatients who underwent hip preservation surgery exhibited significant improvement in iHOT-12 scores, surpassing the minimal clinically important difference at 6 months postoperatively. This improvement plateaued by 2 years, with a slight decline in scores between 1 and 2 years following hip arthroscopy, though the decrease remained within the clinically meaningful range. BMI, age and sex influenced score trajectories, highlighting the importance of setting patient expectations pre-operatively.
