Risk Factors for Spinal Cord Monitoring Alerts in Paediatric Patients Undergoing Spinal Deformity Surgery.
Article in Cureus, 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
backgroundIntraoperative neurophysiological monitoring (IONM) is a standard practice during spinal deformity surgery, but evidence in paediatric patients is limited. This retrospective study aims to identify factors associated with IONM alerts during paediatric spinal deformity surgery.
methodsPatients ≤18 years old who underwent scoliosis correction surgery in a single institute between 2017 and 2022 were reviewed. Analysed factors included estimated blood loss (EBL), operative time, pre- and postoperative major Cobb angles, and mean corrective rate.
resultsAmong 216 cases, eight had significant IONM alerts. These patients had a significantly longer operative time (p = 0.030), preoperative major Cobb angle (p = 0.048) and postoperative major Cobb angle (p = 0.019). Age (p = 0.481), sex (p = 0.416), mean corrective rate (p = 0.799) and EBL (p = 0.062) did not differ significantly. Alerts were found to be primarily triggered by rod application and curve correction (62.5%), screw insertion (25.0%) and corpectomy (12.5%). In the alert group, no patients experienced postoperative neurological deficits, and one operation (12.5%) was aborted. One patient (0.5%) in the non-alert group developed a transient postoperative foot drop but recovered completely nine weeks later. Conclusion: Greater operative time and preoperative and postoperative major Cobb angles were associated with IONM alerts. Most alerts occur during and after the insertion of instrumentation and curve correction manoeuvres. The triggering event should be reversed immediately, and if signals do not recover, surgery should be aborted and staged to prevent neurological deficit.
