1 · What the graph read from it

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.

2 · The registry

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

backgroundWe evaluated the diagnostic value of homocysteine (Hcy) levels combined with the Wells score and established a prediction model for venous thromboembolism (VTE) occurrence in patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPD) based on the Hcy level and the Wells score. PATIENTS AND

methodsClinical information from 914 patients with AECOPD was retrospectively collected in our hospital from June 2020 to October 2023. Receiver operating characteristic curves were plotted to evaluate the diagnostic ability of Hcy concentrations combined with Wells scores and the prediction ability of the model. Univariate and multivariate logistic regressions were used to explore the effects of Hcy levels and the Wells score on VTE occurrence. A nomogram was established for individual risk evaluation.

resultsHcy levels and Wells scores were significantly greater in the VTE group than in the non-VTE group (P < 0.001). The diagnostic ability of Hcy levels combined with the Wells score was greater than that Hcy levels or the Wells score alone. The AUC of the combined parameters was 0.935, with a sensitivity of 0.864 and a specificity of 0.855. Multivariate logistic regression indicated that elevated Hcy levels (OR:5.17, 95%CI: 3.76-7.09, P < 0.001) and Wells score (OR: 5.26, 95%CI: 3.22-8.59, P < 0.001) were independently associated with the risk of developing VTE in AECOPD patients. Decision curve analysis indicated that the net benefit of the nonadherence prediction nomogram was greater than that of the models adjusted for no or all variables, with a threshold of approximately 0.1-1.0.

conclusionsThe established prediction model can be used to evaluate an individual's risk of developing VTE on the basis of the Hcy level, Wells score, and clinical parameters. AECOPD patients may benefit from the early intervention based on estimated risk probability.
