Risk Factors for Neurological Complications in Severe Spinal Deformity Surgery.
Article in Orthopaedic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveSevere spinal deformities, including scoliosis and kyphosis, present significant challenges in corrective surgery due to the elevated risk of neurological complications. The identification of preoperative risk factors is of paramount importance for the optimization of outcomes and the prevention of complications.
methodsThis retrospective cohort study analyzed 130 patients with severe spinal deformities who underwent surgical treatments from January 2002 to May 2022. A comprehensive collection and analysis of preoperative clinical, imaging, and surgical data were conducted with the objective of identifying risk factors for neurological complications. Univariate and multivariate logistic regression analyses were conducted to ascertain the independent predictors.
resultsA total of 130 patients were included in the study, with a female ratio of 50% and a mean age of 21.4 ± 15.3 years, and 18 (13.8%) of them experienced postoperative neurological complications. Significant factors included preoperative spinal cord anomalies (38.9% in the complication group vs. 8.9% in the non-complication group, p = 0.001) and a higher kyphosis angle (112.4° in the complication group vs. 98.2° in the non-complication group, p = 0.018). The incidence of intraoperative neuromonitoring alarms was significantly higher in the complication group (38.9% vs. 15.9%, p = 0.022). No significant differences were observed in operative time (p = 0.095) or blood loss (p = 0.179). A higher angle of kyphosis (OR = 1.027, 95% CI: 1.001-1.055, p = 0.045) and the occurrence of spinal cord anomalies (OR = 6.715, 95% CI: 1.694-26.615, p = 0.007) were independent predictors of surgical neurological complications.
conclusionsPreoperative spinal cord anomalies and a higher kyphosis angle are independent risk factors for postoperative neurological complications. A comprehensive preoperative evaluation is essential for optimizing surgical strategies in these high-risk patients.
