Prevalence and risk factors for postoperative atrial fibrillation following pulmonary resection: a systematic review and meta-analysis.
Synthesis in Journal of cardiothoracic 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
objectiveThis study aimed to perform a meta-analysis integrating multiple sources to investigate risk factors for postoperative atrial fibrillation (POAF) in patients undergoing pulmonary resection (PR).
methodsWe searched English databases (PubMed, Cochrane Library, Embase, Web of Science (WOS)) and Chinese databases (China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP Database, Sinomed) up to September 25, 2025. Observational studies utilizing multivariate logistic regression to analyze the prevalence and risk factors of atrial fibrillation (AF) following PR were selected. Meta-analysis was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Data were extracted, and pooled odds ratios (OR) with 95% confidence intervals (CI) were calculated using STATA 15.0.
resultsEighteen studies involving 25,238 patients were included, among whom 1,967 developed POAF, yielding a prevalence of 7.79%. Meta-analysis revealed significant associations between POAF and the following risk factors: Age (OR = 1.04, 95% CI: 1.01–1.06, p = 0.011), Age ≥ 65 years (OR = 2.92, 95% CI: 2.02–4.23, p < 0.001), Male (OR = 1.93, 95% CI: 1.46–2.56, p < 0.001), Hypertension (OR = 1.34, 95% CI: 1.14–1.57, p < 0.001), Lymph node dissection (OR = 2.18, 95% CI: 1.12–4.24, p = 0.021), Thoracotomy (OR = 1.71, 95% CI: 1.40–2.09, p < 0.001), Lobectomy (OR = 2.68, 95% CI: 1.05–6.81, p = 0.039), Pneumonectomy (OR = 4.33, 95% CI: 2.12–8.84, p < 0.001), Operative time (minutes) (OR = 1.05, 95% CI: 1.01–1.09, p = 0.026), History of hyperthyroidism (OR = 5.67, 95% CI: 1.97–16.32, p < 0.001), Pre-existing atrial fibrillation (Pre-existing AF) (OR = 15.79, 95% CI: 4.69–53.13, p < 0.001), Red blood cell transfusion (OR = 2.78, 95% CI: 2.22–3.47, p < 0.001). No significant association was found with video-assisted thoracoscopic surgery (VATS) (OR = 1.02, 95% CI: 0.29–3.61, p = 0.97).
conclusionThis study suggests that POAF following PR is associated with multiple patient- and surgery-related risk factors, many of which are identifiable preoperatively. Pre-existing AF was identified as the strongest predictor among the factors analyzed. These findings support the rationale for integrating preoperative risk assessment into the planning of individualized postoperative monitoring and prevention strategies, which may help improve clinical outcomes.
