Local bone graft in adolescent idiopathic scoliosis surgery: a systematic review and meta-analysis.
Synthesis in Spine deformity, 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
purposeIn many centers, extra bone graft or bone substitute is used in routine surgery for adolescent idiopathic scoliosis (AIS). We examined the existing evidence to determine whether local bone graft (LBG) alone is sufficient.
methodsWe performed the literature search through PubMed and Web of Science, using the search terms "scoliosis" and "bone graft." The inclusion criteria were primary posterior AIS surgery, the use of LBG exclusively, and segmental placement of anchors. Studies that provided a control group were added to the meta-analysis. The Risk of Bias in Non-Randomized Studies of Interventions (ROBINS-I) tool and version 2 of the Risk of Bias tool for randomized trials (RoB 2) was used. The inverse variance method and the random effects model meta-analysis were chosen.
resultsSix studies involving 549 patients were eligible. One study reported occasional use of posterior column osteotomy. Adding bone graft did not reduce the occurrence of pseudoarthrosis (odds ratio 0.94; 95% confidence interval 0.40-2.22; p = 0.89; I
conclusionsLBG can be used alone in AIS patients with posterior segmental instrumentation. Extra material may not be needed in routine cases.
