Risk factors for postoperative venous thromboembolism in patients with lung cancer: a systematic review and meta-analysis.
Synthesis in Frontiers in medicine, 2025. 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
Objective: Venous thromboembolism (VTE) is a serious complication following lung cancer surgery, which not only complicates treatment but may also delay cancer-specific therapies and even threaten patient survival. Currently, the risk factors for postoperative VTE in lung cancer patients remain unclear. Therefore, we conducted a meta-analysis to identify risk factors associated with VTE in these patients after surgery. Methods: We systematically searched PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Database, Chinese Biomedical Literature Database (CBM), and VIP Database for studies investigating risk factors for VTE after lung cancer surgery. The search covered the period from database inception to February 2025. Two reviewers independently screened the literature based on the inclusion and exclusion criteria, extracted data, and assessed the risk of bias in the included studies. Meta-analysis was performed using RevMan 5.4 software. Results: A total of 21 studies involving 41,780 participants were included. The meta-analysis identified the following significant risk factors for VTE after lung cancer surgery: age ≥ 65 years old, hyperlipidemia, tumor staging III-IV, thoracotomy, operation time ≥ 2 h, intraoperative blood loss ≥ 200 mL, abnormal D-dimer levels, and preoperative chemotherapy. In contrast, no statistically significant associations were found between VTE occurrence and sex, age ≥ 60 years, smoking history, drinking history, body mass index ≥ 25 kg/m Conclusion: This meta-analysis confirmed that age ≥ 65 years, hyperlipidemia, advanced tumor stage (III-IV), thoracotomy, prolonged operation time (≥ 2 h), significant intraoperative blood loss (≥ 200 mL), abnormal D-dimer, and preoperative chemotherapy were risk factors for VTE in lung cancer patients after surgery. Targeted preventive measures based on these factors may help improve clinical outcomes in this patient population.
