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

objectivesTo estimate the overall risk of venous thromboembolism (VTE), pulmonary embolism (PE) and deep vein thrombosis (DVT) among patients newly diagnosed with RA compared with the general population without RA; and to estimate the risk trends of VTE, PE and DVT after RA diagnosis up to 5 years compared with the general population.

methodsUsing previously validated RA case definition, we conducted a matched cohort study using the population-based administrative health database from the province of British Columbia, Canada. We calculated incidence rates (IRs) and fully adjusted hazard ratios (HRs) for the risk of VTE, DVT and PE after RA index date.

resultsAmong 39 142 incident RA patients (66% female, mean age 60), 1432, 543 and 1068 developed VTE, PE and DVT, respectively. IRs for the RA cohort were 3.79, 1.43 and 2.82 per 1000 person-years vs 2.70, 1.03 and 1.94 per 1000 person-years for the non-RA cohort. After adjusting for VTE risk factors, the HRs (95% CI) were 1.28 (1.20, 1.36), 1.25 (1.13, 1.39) and 1.30 (1.21, 1.40) for VTE, PE and DVT, respectively. The fully adjusted HRs for VTE during the first five years after RA diagnosis were 1.60, 1.47, 1.40, 1.30 and 1.28, respectively. A similar trend was shown in PE.

conclusionThis population-based study demonstrates that RA patients have an increased risk of VTE, PE and DVT after diagnosis compared with the general population. This risk is independent of traditional VTE risk factors and is highest during the first year after RA diagnosis, then progressively declined.
