ANCA-associated vasculitis is associated with an increased risk of cardiac and vascular morbidity: results of a large-scale propensity-matched global retrospective cohort study.

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
Introduction: Despite significantly improved therapies in recent years, long-term morbidity and mortality in ANCA-associated vasculitis (AAV) remain high. The leading causes of death within the first year after diagnosis are active vasculitis and in subsequent years cardiovascular diseases, malignancies, and infections. Population-based database and cohort analyses suggest an increased risk for major adverse cardiovascular events (MACE) in AAV. Methods: This retrospective cohort study analyzed data samples from an electronic health records database of the US-based TriNetX network. Patients with the diagnostic codes granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA) and patients without vasculitis as a matched control cohort (1:1) were included. To optimize between-group comparability, propensity score matching was performed for demographic variables and comorbidity. Hazard ratios (HR) for death and cardiovascular outcomes were calculated using univariate Cox regression after analyzing the matched cohort using the Kaplan-Meier method. Results: We identified 20, 422 patients with GPA and 5, 907 with MPA. Mortality was more frequent in patients with GPA (17.87%) and MPA (25.85%) than in matched controls (GPA controls: 5.79%; MPA controls: 9.70%), corresponding to an increased hazard of death in both cohorts (GPA: HR 3.01; MPA: HR 3.01). The risk of cardiovascular events was increased in GPA and MPA compared to matched controls, particularly for MACE (GPA: HR: 1.94, MPA: HR: 2.24) and thromboembolic events (deep vein thrombosis: GPA HR: 2.82, MPA HR: 3.33; pulmonary embolism: GPA HR: 3.01, MPA HR: 3.00) and did not differ when adjusted according to sex, disease duration, and age. Compared with GPA patients, MPA patients had a higher risk of MACE (HR: 1.13) and peripheral arterial disease (HR: 1.17). Conclusion: AAV was associated with an increased risk of death and cardiovascular events. Compared with GPA, MPA was associated with an increased risk for MACE and peripheral arterial disease.
