Effect of Sociodemographic Differences on Elective Lumbar Fusion Surgery.

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
introductionSociodemographic differences markedly affect postoperative outcomes in lumbar fusion surgery, often leading to higher infection rates, readmissions, emergency department (ED) visits, and prolonged hospital stays. This study examines the associations between sociodemographic factors and clinical outcomes after elective lumbar fusion surgery.
methodsWe retrospectively analyzed medical records of patients aged ≥18 years who underwent lumbar or lumbosacral fusion for degenerative conditions from 2018 to 2022 at a single academic institution. ED returns and readmissions within 3 months were also recorded. Statistical analysis was conducted using chi-square tests, t-tests, ANOVA, and multivariate logistic regression models.
resultsA total of 484 patients (54.1% male) were included. Most patients were White (80.4%) and non-Hispanic (91.5%). Men exhibited lower ED utilization (16% versus 23%) and readmission (11.5% versus 19.8%) rates than women. Men were more frequently discharged home (87%) compared with women (79.3%), with fewer discharges to skilled nursing or rehab facilities. No significant differences in length of stay, readmission, ED return, or discharge disposition were observed across racial groups. The private insurance group had shorter hospital stays (3.1 ± 1.7 days) than Medicare/Medicaid patients (3.8 ± 2.6 days) and other groups (4.7 ± 3.3 days, P = 0.005). Medicare/Medicaid patients had higher ED return and readmission rates and were less likely to be discharged home (P < 0.001). Multivariate models revealed that sex and payer status significantly affected readmissions and discharge dispositions.
conclusionWomen and Medicare/Medicaid patients experience poorer postoperative outcomes, with increased ED visits and readmissions after lumbar fusion surgery. Race did not significantly affect outcomes, although small sample sizes may have limited this analysis.
