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
introductionThoracic hyperkyphosis can occur idiopathically, in the context of Scheuermann's disease, or in association with neuromuscular or metabolic disorders. Treatment depends on the patient's age, severity of the deformity, and underlying conditions. Conservative measures such as physiotherapy and reclination bracing are used in mild cases, whereas surgical correction is indicated for kyphosis exceeding 60-70°. A known association exists between hyperkyphosis and pectus excavatum, the latter of which can cause cardiac symptoms. However, the impact of surgical kyphosis correction on cardiac symptoms in patients with concurrent pectus excavatum remains unclear. CASE PRESENTATION: We present the case of a boy born in 2006 with progressive thoracic hyperkyphosis and pectus excavatum. Despite conservative therapy involving physiotherapy and bracing, the deformity progressed. In December 2023, a dorsal correction spondylodesis (Th6-L2) with Smith-Peterson osteotomies (Th8-L1) was performed. The kyphosis was corrected from 108° to 42°. Postoperatively, the patient developed tachycardia and dizziness. A pericardial effusion and a newly diagnosed right bundle branch block were detected. Radiological evaluation showed a reduction in the retrosternal space from 7.5 cm to 5.2 cm. Subsequently, surgical correction of the pectus excavatum was performed, leading to the resolution of symptoms and an increase in the retrosternal space to 8.7 cm. DISCUSSION: This case study demonstrates that surgical correction of thoracic hyperkyphosis in the presence of pectus excavatum can lead to the clinical manifestation of previously asymptomatic cardiac issues. Due to the biomechanical interaction between the spine, ribs, and sternum, deformities in this region can influence each other. We recommend checking preoperatively whether pectus excavatum is present and then correcting it surgically as a priority to avoid cardiac complications.
