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

objectiveVenous thromboembolism (VTE) is an increasing concern in rheumatoid arthritis (RA) with little known about risk factors. We aimed to compare risk factors for unprovoked VTE and atherosclerotic cardiovascular disease (ASCVD) in patients with RA and to assess subsequent ASCVD risk after an unprovoked VTE.

methodsPeople with RA participating in a US-wide longitudinal observational registry from 1998 to 2018 were assessed for incident unprovoked VTE (deep venous thrombosis and pulmonary emboli not associated with cancer, recent surgery, hospitalisation, fracture and pregnancy) and ASCVD (myocardial infarction and stroke) validated from hospital/death records. Risk factors for VTE and ASCVD and the risk of ASCVD after an unprovoked VTE were determined using Cox proportional hazards models.

resultsDuring median (IQR) 4 (1.5-7) years of follow-up in 31 366 patients with RA, 539 unprovoked VTE and 1648 ASCVD events were identified. The adjusted models showed increased VTE and ASCVD risk with older age, male sex, comorbidities, prior fracture, worse disability, higher disease activity and glucocorticoids. Traditional cardiovascular disease risk factors were common in both ASCVD and VTE but only increased ASCVD risk with obesity as the exception (VTE HR (95% CI), 1.46 (1.13-1.87)) and ASCVD, 0.58 (0.50-0.68)). ASCVD risk doubled after an unprovoked VTE (HR (95% CI), 2.05 (1.43-2.95)).

conclusionOur findings suggest that unprovoked VTE is mediated by inflammation of RA and may be considered a spectrum of pan-cardiovascular syndrome.
