Evaluation of a Pediatric Surgical Risk Calculator for Postoperative Outcomes in Spinal Deformity.
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 evaluate the accuracy of the ACS-NSQIP Pediatric Surgical Risk Calculator in predicting postoperative complications and mortality following pediatric spinal deformity surgery. Predicted risks were compared with observed outcomes from the ACS-NSQIP Pediatric database, stratified by scoliosis etiology, fusion level, and surgical approach.MethodsWe performed a retrospective analysis of pediatric patients who underwent spinal deformity correction between 2012 and 2023 using the ACS-NSQIP Pediatric database. Patients were categorized as idiopathic or neuromuscular scoliosis. Predicted risks were compared with observed 30-day outcomes including mortality, surgical site infection, pneumonia, and urinary tract infection. Predictive performance was assessed using the Brier score across discrimination and calibration dimensions.ResultsA total of 58,010 patients were included (45,211 idiopathic; 12,799 neuromuscular). Overall, the calculator predicted a 2.74% complication rate vs an observed rate of 9.54% (Brier: 0.00462; 5.35% of maximum), reflecting poor discrimination and substantially underestimated absolute risk. The most frequent complications were surgical site infection (2.12%), pneumonia (0.99%), and urinary tract infection (0.64%), each demonstrating adequate individual-level discrimination and calibration. Stratified analyses showed adequate performance for idiopathic scoliosis patients undergoing 0-12 level fusions, while discrimination was poor for ≥13 level fusions. Performance was substantially worse among neuromuscular scoliosis patients across all fusion levels. Surgical approach did not meaningfully affect performance.ConclusionsThe calculator reliably predicts select individual complications but underestimates overall risk in high-complexity cases, particularly extensive fusions and neuromuscular scoliosis. Incorporating deformity-specific and surgical complexity variables may improve preoperative risk stratification and counseling.
