Biomarkers of Prothrombotic State and Risk Assessment of Exacerbations in Patients with Chronic Obstructive Pulmonary Disease.
Article in International journal of chronic obstructive pulmonary disease, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Background: Epidemiologic studies have shown that patients with acute exacerbation of COPD (AECOPD) suffer from morbidity and mortality from venous thromboembolism (VTE) and poor diagnosis. Von Willebrand factor (vWF) and plasminogen activator inhibitor type-1 (PAI-1) are frequently investigated in COPD as crucial parameters for coagulation and fibrinolysis. Nevertheless, the role of vWF and PAI-1 in AECOPD needs further exploration. Objective: We sought to evaluate the hypercoagulability in AECOPD and investigate the association of plasma vWF and PAI-1 with occurrence and exacerbation risk of AECOPD patients. Methods: Fifty-seven AECOPD patients and 34 control subjects were enrolled in our study. The concentrations of plasma vWF and PAI-1 antigens were measured by ELISA kit. Independent samples Results: We observed increased vWF (770.15 ± 325.52 vs 327.62 ± 210.97 ng/mL, P < 0.001) and PAI-1 (0.47 vs 0.17 ng/mL, P < 0.001) levels in AECOPD patients compared with control subjects. Both vWF and PAI-1 are closely related to COPD (vWF: AUC = 0.8741, P < 0.001; PAI-1: AUC = 0.8222, P < 0.001). Moreover, elevated vWF could be an independent risk factor for COPD (OR = 1.01, 95% CI: 1.00-1.01, P = 0.01). We also discovered higher plasma levels of vWF and PAI-1 in the COPD "E" group in contract to "AB" group (vWF: 966.29 ± 251.18 vs 552.21 ± 253.28, P < 0.0001; PAI-1: 1.02 vs 0.38, P = 0.003). And vWF levels increased with increasing COPD exacerbation risk, moreover, plasma vWF positively related with patients' CAT scores and SGRQ scores. In addition, plasma vWF and PAI-1 correlated with each other in total participants and AECOPD subgroup analysis. Conclusion: This study demonstrated that AECOPD patients have a prothrombotic state, as demonstrated by vWF and PAI-1 levels in plasma compared with those in control subjects, and the prothrombotic state increases with increasing COPD exacerbation risk.
