Sagittal Profiles and Their Reciprocal Changes Manifesting in Proximal Junctional Kyphosis Following Deformity Correction in Adolescent Idiopathic Scoliosis.
Article in Global spine journal, 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
Study DesignRetrospective cohort study.ObjectivesTo investigate sagittal profiles including sagittal shape and alignment in relation to proximal junctional kyphosis (PJK) following deformity correction in patients with adolescent idiopathic scoliosis (AIS).MethodsA total of 282 AIS patients who underwent deformity correction were categorized into 2 groups according to the presence of PJK at the 2-year follow-up: the PJK group (n = 48) and the non-PJK group (n = 234). Sagittal shape was classified as normal thoracic kyphosis (TK), hypo-TK with/without thoracolumbar kyphosis (TLK), and cervico-thoracic kyphosis. Changes in Roussouly classification and correction relative to the functional T10 pelvic angle target were assessed to evaluate sagittal restoration and its association with PJK.ResultsThe upper instrumented vertebra (UIV) level differed significantly between the 2 groups (
