Predictors for postoperative gastrointestinal complications in pediatric non-idiopathic scoliosis patients.
Article in Spine deformity, 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
purposeNon-Idiopathic scoliosis (NIS) patients reportedly have higher postoperative complication rates compared to those with adolescent idiopathic scoliosis (AIS). However, there are limited data on the prevalence of gastrointestinal (GI) complications postoperatively, and the preoperative indicators that may predict them. This study aimed to determine the incidence and risk factors of postoperative gastrointestinal (PG) complications after neuromuscular/syndromic scoliosis corrective surgery.
methods163 NIS patients underwent spine deformity corrective procedure between 2005 and 2020. Radiographic, surgical, and clinical data were assessed. Patients were stratified based on postoperative GI complication status (PG vs. NPG) and ambulatory status (AMB vs. NAMB, based on GMFCS levels). Clavien-Dindo-Sink classification system was used to separate surgical complications based on severity. Wilcoxon-Rank Sum, Fisher's Exact, Chi-square, and McNemar's tests were utilized. Multivariable logistic regression was conducted. Matched analysis between NIS and AIS patients was conducted with 13 + levels fused.
resultsThere were 163 patients; 40 (24.5%) patients developed postoperative GI (PG) complications. The overwhelming majority of PG patients (39/40 patients, 97.5%) exhibited one or more minor complications with only 2/40 (5%) major complications; one patient had both 1 major and 1 minor. A greater portion of PG patients had pre-existing GI comorbidities (p < 0.001) and were non-ambulatory (p = 0.003). Non-ambulatory patients had more pre-existing GI comorbidities (< 0.001) and GI complications (p = 0.003) than ambulatory patients. Patients with pre-existing GI diseases had 5.34 times greater odds of developing a postoperative GI complication (p < 0.001), specifically those with a G-tube and followed by GI.
conclusionNon-ambulatory patients are more likely to exhibit GI complications. Pre-existing GI comorbidities, specifically G-tube and being actively followed by a GI specialist are high risk factors for postoperative GI complications.
