Sociodemographic variables are rarely reported in randomized controlled trials investigating posterior spinal fusion for adolescent idiopathic scoliosis: A systematic review.
Review in Journal of children's orthopaedics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Adolescent idiopathic scoliosis (AIS) develops between the ages of 10 and skeletal maturity and can lead to physical, psychosocial, and medical complications if untreated. Posterior spinal fusion (PSF) is the primary surgical intervention when bracing fails. Although sociodemographic factors affect access to care, surgical candidacy, perioperative risk, and recovery, these variables are rarely reported in randomized controlled trials (RCTs), limiting assessment of equity and generalizability in AIS outcomes. Methods: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, PubMed, Embase, and Scopus were searched on 9 April 2024, using "posterior spinal fusion," "randomized controlled trial," and "adolescent idiopathic scoliosis." Inclusion criteria were full-text RCTs on PSF in AIS; exclusions were non-English publications, cadaver studies, and technique articles. Two authors independently screened studies, with disagreements resolved by a third. Extracted variables included demographics and social factors. Analyses used descriptive statistics, chi-squared tests, and Fisher's exact test ( Results: Of 148 studies, 44 met the inclusion criteria. Age (97.7%) and sex (95.5%) were reported more frequently than race (6.8%) or ethnicity (9.1%) ( Conclusions: RCTs on PSF for AIS rarely report sociodemographic variables beyond age and sex. This gap limits understanding of whether outcomes are consistent across populations or if disparities exist in treatment response or recovery. Improved sociodemographic reporting is essential for transparency, external validity, and equity in AIS care. Level of Evidence: Systematic review of Level II.
