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
backgroundCongenital scoliosis is one of the most common spinal deformities, often leading to underdevelopment of cardiopulmonary function in children, and may even result in severe cardiopulmonary damage, including respiratory failure and cor pulmonale. Most hemivertebral deformity scoliosis progresses rapidly, and conservative treatment is generally ineffective, ultimately requiring surgical intervention. This study evaluates the surgical outcomes of posterior hemivertebrectomy combined with short-segment fusion and pedicle screw fixation for congenital scoliosis, with a mean follow-up of 2.5 years.
methodsThis is a retrospective study that included 24 patients with hemivertebral scoliosis who underwent posterior hemivertebrectomy combined with short-segment fusion between 2017 and 2023, with an average follow-up period of 2.5 years (ranging from 1.4 to 5 years). Surgical records and radiological assessments were reviewed. Surgical records included operation time, blood loss, transfusion volume, and postoperative complications. Radiological evaluations included segmental scoliosis, compensatory scoliosis, segmental kyphosis, coronal plane trunk balance, and measurement of pedicle screw placement accuracy.
resultsAmong the 24 patients, 15 were male and 9 were female, with an average age of 5.4 years (ranging from 2.8 to 11.7 years), and an average follow-up of 29.4 months (ranging from 19 to 60 months). The preoperative mean segmental scoliosis was 37.92°, which was corrected to 10.79° postoperatively (correction rate 73.22%), and was 12.42° at the last follow-up (correction rate 68.52%) (P < 0.001). Postoperative compensatory scoliosis automatically corrected from 16° preoperatively to 5.79°, and was 7.54° at the last follow-up (P < 0.001). Coronal plane trunk deviation was corrected from 25.17 mm preoperatively to 11.17 mm, and remained stable during follow-up, measuring 11.99 mm at the last follow-up (P < 0.001). In the sagittal plane, segmental kyphosis was corrected from 24.04° preoperatively to 10.04° postoperatively (correction rate 53.53%), and was 12.42° at the last follow-up (correction rate 40.1%). From preoperative to last follow-up, segmental scoliosis, compensatory scoliosis, coronal plane trunk deviation, and segmental kyphosis showed significant correction (p < 0.001). However, there was no significant difference between postoperative and last follow-up assessments (P > 0.05). Two patients experienced transient neurological injury after surgery.
conclusionPosterior hemivertebrectomy combined with short-segment fusion demonstrates good efficacy in the treatment of congenital scoliosis, effectively correcting spinal deformities with a low incidence of postoperative complications. Excellent correction was maintained during mid- to short-term follow-up.
