Balancing radiographic correction with quality of life: a meta-analysis of selective versus non-selective thoracic fusion in Lenke 1 C AIS.

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
backgroundThe optimal surgical strategy for Lenke 1 C adolescent idiopathic scoliosis (AIS) remains debated. Selective thoracic fusion (STF) preserves lumbar mobility by limiting fusion to the thoracic curve, while non-selective thoracic fusion (NSTF) extends distally to address the thoracolumbar/lumbar (TL/L) curve. The comparative long-term impact of these strategies on health-related quality of life (HRQoL) remains uncertain.
methodsA systematic search was performed in PubMed, Scopus, Cochrane Library, and Google Scholar till September 2025. Five studies met the inclusion criteria. Key outcomes included perioperative outcomes (operative time and blood loss), radiographic parameters (state them with abbreviations), and HRQoL assessed with SRS-22r or SRS-30, pooled using a random-effects model.
resultsSTF was associated with significantly shorter operative time (MD - 76.21 min, p < 0.001) and reduced blood loss (MD - 27.30 mL, p = 0.02). No difference was observed in MT Cobb angle correction at 2 years (p = 0.17). NSTF achieved superior TL/L outcomes, with a smaller residual Cobb angle (MD 5.14°, p = 0.04) and a higher correction rate (MD - 23.65%, p < 0.001). HRQoL analysis showed no significant differences between groups in any domain, including function/activity, pain, self-image/appearance, mental health, satisfaction with management, or in total score (all p > 0.05).
conclusionsSTF reduces surgical burden and preserve lumbar motion, while NSTF achieves superior TL/L correction. Yet, these differences did not translate into significant HRQoL variation, suggesting that in borderline Lenke 1 C patients, surgical decision-making should not rely on radiographic outcomes alone but also integrate patient-centered and subjective considerations.
