Increased Age at Time of Spinal Fusion Does Not Increase Risk of Adverse Outcomes: A Propensity Score-Matched Multicenter Retrospective Cohort Study.
Article in International journal of spine surgery, 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
backgroundThe US population is aging, with the number of individuals aged 85 or older expected to triple by 2060. As such, spine surgeons are operating on an increasing number of elderly patients. This propensity score-matched retrospective analysis aimed to determine whether 30-day postoperative outcomes from spinal fusion surgery differ between super-elderly patients (aged ≥85 years) and younger patients (≤65 years).
methodsPatients in the 2015 to 2023 National Surgical Quality Improvement Program datasets were included if they were treated by an orthopedic or neurological surgeon with a primary Current Procedural Terminology code corresponding to spinal fusion at any level. Patients were separated into a younger cohort (≤65 years) and a super-elderly cohort (≥85 years). Propensity score matching was performed to balance demographics, comorbidities, surgical indications, and specific surgical procedures. Univariate statistical analysis followed by false-discovery rate correction was performed using Python 3.10.16.
resultsFollowing matching, there were 1298 patients in each cohort. There was a 2.6% higher rate of pneumonia (
conclusionsAlthough we identified statistically significant increases in the risk of several adverse outcomes in the super-elderly population, the magnitude of these differences ranged from 1.2% to 2.6%, implying minimal clinical significance. Considering the increased risk of medical complications independent of surgical intervention in the super-elderly population, the minor increase in the risk of complications observed in this study can be considered acceptable, suggesting that advanced age alone is not a contraindication to surgery. CLINICAL RELEVANCE: The results of this study provide insights into the safety of spinal arthrodesis in the growing super-elderly population. LEVEL OF EVIDENCE: 4:
