1 · What the graph read from it

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.

2 · The registry

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

introductionPatients with neuromuscular diseases frequently develop hip displacement (HD) and scoliosis, creating complex challenges in determining the optimal treatment strategy and sequence. This study aims to assess the frequency of new hip problems, including pain and HD progression, as well as the need for additional hip surgery following scoliosis correction in neuromuscular patients, and to identify predictive factors for these issues.

methodsThis retrospective study included 71 neuromuscular patients (142 hips) who underwent posterior spinal fusion (PSF) at a specialized center between 2015 and 2022. Clinical data such as age, sex, underlying pathology, ambulatory status, and prior hip surgeries were collected. Radiological parameters, including curve characteristics, coronal imbalance, Cobb angle, pelvic obliquity (PO), and migration percentage (MP), were measured pre- and post-operatively. Descriptive, comparative, and multivariate analyses, including logistic regression, were performed to identify significant predictors and determine optimal cutoff points.

resultsThe mean age of patients was 15 ± 2 years, with 59% female and 84.5% nonambulatory. After scoliosis surgery, 15.5% of hips developed new hip problems: 20 hips experienced pain and 9 had HD progression, with 7 requiring additional surgery (3 reconstructive and 4 palliative). Factors including a preoperative up-hip and increased MP, with a cutoff > 25%, were strong predictors of hip pain. HD progression was linked to a postoperative up-hip and increased MP, with MP > 60% emerging as a critical predictor. The need for additional hip surgery was associated with cerebral palsy (CP) and with increased MP.

conclusionsApproximately 1 in 7 hips developed new-onset problems following PSF in neuromuscular patients. Factors including a preoperative up-hip and increased MP were significant predictors of adverse outcomes, underscoring the importance of thorough preoperative assessment, personalized surgical planning, and proactive counseling regarding potential postoperative complications. LEVEL OF EVIDENCE: Level IV, retrospective cohort study.
