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
Functional limitations often persist in patients with venous thromboembolism (VTE). The relevance of biomarkers for these outcomes remains unexplored. Therefore, we aimed to investigate the association of hemostatic, inflammatory, and cardiovascular biomarkers with functional limitations 3 months after VTE. We conducted a prospective cohort study, including patients with acute VTE within 21 days of diagnosis. Biomarker levels (D-dimer, fibrinogen, factor VIII [FVIII], von Willebrand factor antigen [VWF], C-reactive protein [CRP], troponin T, N-terminal pro-B-type natriuretic peptide [proBNP]) were measured at inclusion and 3 months. Functional limitations at 3 months were evaluated with the post-VTE functional status (PVFS) scale (0-4, higher indicating more limitations). The association of biomarkers with functional limitations was assessed with proportional odds models adjusted for confounders. Furthermore, we evaluated the area under the receiver operating characteristic curve (AUC-ROC) for the presence of slight-to-severe functional limitations. Overall, we included 290 patients (41.4% of women) with a median age of 54.9 years (interquartile range [IQR]: 43.1-64.2). D-dimer, fibrinogen, FVIII, VWF, and CRP measured at inclusion were independently associated with functional limitations at 3 months. VWF showed the most favorable AUC-ROC (0.62, 95% CI, 0.55-0.69). In patients with pulmonary embolism, troponin T and proBNP were not associated with functional limitations. At the 3-month follow-up, D-dimer was the only biomarker independently associated with functional limitations, yielding an area under the curve (AUC) of 0.62 (95% CI, 0.55-0.69). In conclusion, we identified biomarkers independently associated with functional limitations 3 months after VTE. Our results indicate a role of these biomarkers in the early identification of patients at risk of persistent functional limitations and suggest their involvement in the underlying mechanisms.
