What factors predict cervical sagittal alignment restoration after correction of thoracic adolescent idiopathic scoliosis with severe thoracic hypokyphosis? A multicenter retrospective study of 57 patients.

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
purposeto evaluate changes in cervical sagittal alignment after correction of AIS with severe thoracic hypokyphosis (< 10°); to assess radiographical parameters predicting postoperative cervical sagittal alignment through multivariate regression analysis.
methodsA multicenter retrospective study included AIS patients with severe thoracic hypokyphosis. Treatment involved posterior spinal fusion with pedicle screws, Ponte osteotomies, differential rod contouring and DVR. Radiographic analysis was conducted preoperatively and at a minimum 2-year follow-up.
resultsAmong 57 patients, a significant improvement in T5-T12 thoracic kyphosis was noted at the last follow-up. Cervical Lordosis (CL) also significantly increased, with a remaining mismatch between ideal and actual postoperative CL. Correlation analyses revealed associations between thoracic kyphosis and postoperative CL. In patients with preoperative neutral or kyphotic CL, additional factors, such as TK apex-SVA, C5-T2° Change, and TK apex-scoliosis apex distance, correlated with CL changes.
conclusionPosterior correction of hypokyphotic AIS demonstrated significant CL improvement, yet a mismatch between ideal and achieved alignment persisted. The degree of thoracic and cervicothoracic alignment restoration correlated with spontaneous CL improvement. Overall, the study highlights the complexities of sagittal alignment in AIS.
