A multifactorial investigation of 90-day readmission risk in thoracolumbar burst fractures: Does surgery play a role?
Article in North American Spine Society 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
Background: Most spinal fractures occur in the thoracolumbar region, with controversy persisting over operative versus nonoperative treatment paradigms for neurologically intact thoracolumbar burst fractures (TLBF). This study sought to determine the readmission rate, risk factors, and total hospital charges within 90 days of TLBF. Methods: Using International Classification of Diseases, Tenth Revision (ICD-10) codes, we retrospectively reviewed all adult patients in the 2018 United States Healthcare Utilization Project Nationwide Readmissions Database with a new single-level TLBF from January to September 2018. We assessed readmissions, operative versus nonoperative treatment, demographics, comorbidities, charges, and payer status. Results: We identified 4,395 TLBF patients, with 1,857 (42%) treated operatively and 2,538 (58%) treated nonoperatively. There was a 7.0% unplanned 90-day readmission rate in the overall cohort. For readmitted patients, 69 (22.5%) were treated operatively, and 238 (77.5%) were treated nonoperatively. Patients treated operatively were less likely to undergo readmission (adjusted odds ratios [aOR]=0.39, 95% confidence interval [CI]=0.29-0.53, p<.001), though operative management was associated with substantial charges (mean $161,728, 95% CI $153,720-$169,735, p<.001). Total hospital charges were significantly greater in readmitted patients ($224,445±$184,681) than in nonreadmitted patients ($131,783±$148,029, p<.001). Patients with obesity (p<.0001, aOR=2.04, 95% CI=1.5-2.8), coagulopathy (p=.05), pain syndromes (p<.01), and/or bipolar disorder (p<.01) were significantly more likely to be readmitted, as were patients with Medicare when compared to those with Medicaid, private insurance, or self-pay (p<.01). Operatively treated patients with nutritional deficiencies demonstrated the highest odds for readmission (aOR=3.5, 95% CI=1.41-8.8, p<.01), suggesting surgical caution for these patients. Conclusions: We observed a 7.0% 90-day readmission rate for neurologically intact TLBF patients with key comorbidities associated with increased risk. Recognition of these comorbidities may aid clinicians in counseling patients and considering operative versus nonoperative management of neurologically intact TLBF.
