Atrial fibrillation versus non-atrial fibrillation in postoperative complications following lumbar surgery: a retrospective case-control study.
Article in Perioperative medicine (London, England), 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
backgroundWith an aging population and high prevalence rate of atrial fibrillation (AF) in older individuals, more elderly patients with AF receive lumbar operations. Nevertheless, there has been little study discussing the perioperative outcomes of AF in lumbar surgery, especially using a national database.
methodsA population-based, retrospective cohort survey was conducted on adults receiving lumbar surgery who were divided into 2 cohorts based on the diagnosis of AF or not, using the 2016–2019 Nationwide Inpatient Sample database. Propensity score matching was applied to eliminate selection bias. Univariate and multivariate analyses were performed to explore the impact of AF on postoperative complications following AF.
resultsOverall, 222,557 lumbar surgical patients were finally involved in the present study, 10,929 (4.9%) of whom had AF. Irrespective of potential confounders, the in-hospital death risk of patients undergoing lumbar surgery with AF was 1.75-fold compared to those without AF. Additionally, AF was an apparently independent risk factor for cardiac arrest, postoperative delirium, pneumonia, pulmonary embolism, acute respiratory failure, continuous trauma ventilation, acute renal failure, urinary tract infection, gastrointestinal bleeding, blood transfusion, pyemia, septicemia, death, wound infection, and hemorrhage/hematoma/seroma.
conclusionAF seems to be associated with increased perioperative mortality and complications. Orthopedists should be cognizant of the adverse impact on patients with AF.
