Impact of Bone Graft Type on Spinal Fusion Outcomes in Adolescent Idiopathic Scoliosis: Updated Meta-Analysis.
Article in Journal of bone metabolism, 2025. 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
backgroundPosterior spinal fusion is performed for severe adolescent idiopathic scoliosis (AIS), with bone graft playing a critical role in achieving solid fusion. Iliac crest bone graft (ICBG) is the gold standard but has donor site morbidity, leading to increased use of non-ICBG. This study compared the effectiveness and safety of ICBG and non-ICBG bone grafts in AIS.
methodsThis meta-analysis included 23 studies with 3,350 patients, categorized into ICBG and non-ICBG groups. The primary outcome was fusion rate; secondary outcomes were implant-related complication rate, infection rate, donor site pain, blood loss, and operation time. A proportion meta-analysis was conducted to estimate binary outcomes, and a weighted mean model was used to estimate continuous variables.
resultsThe fusion rate was 97% (95% confidence interval [CI], 93-99) in ICBG group and 97% (95% CI, 95-98) in non-ICBG group. Implant-related complications occurred in 5% (95% CI, 3-7) and 4% (95% CI, 2-6) of each group, while surgical site infections occurred in 3% (95% CI, 2-7) and 2% (95% CI, 1-3). Donor site pain was observed exclusively in ICBG group, with a prevalence of 49% (95% CI, 3-97). Estimated pooled blood loss was 1,461.10 mL (95% CI, 545.30-2,376.90) in ICBG group and 1,047.45 mL (95% CI, 666.92-1,427.99) in non-ICBG group. The estimated pooled operation time was 246.77 (95% CI, 221.74-271.80) and 232.37 (95% CI, 194.88-269.86) for each group.
conclusionsConsidering both ICBG and non-ICBG demonstrated high fusion rates and low complication rates, non-ICBG grafts may serve as an effective and safe alternative to ICBG, minimizing morbidity, donor site pain, and blood loss.
