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

backgroundIt is not known what diagnoses are associated with an elevated D-dimer in unselected patients attending emergency departments (ED), nor have their associated outcomes been determined.

methodsThis was a prospective observational study of 1612 unselected patients attending a Danish ED, with 100% follow-up for 90 days after presentation.

resultsThe 765 (47%) ED patients with an elevated D-dimer level (ie, ≥ 0.5 mg/L) were more likely to be admitted to hospital (P <.0001), re-present to health services (P = .02), and die within 90 days (8.1% of patients, P <.0001). Only 10 patients with a normal D-dimer level (1.2%) died within 90 days. Five had chronic obstructive pulmonary disease and infection, and 5 had cancer (4 of whom also had infection). Venous thromboembolism, infection, neoplasia, anemia, heart failure, and unspecified soft tissue disorders were significantly associated with an elevated D-dimer level. Of the 72 patients with venous thromboembolism, 20 also had infection, 8 had cancer, and 4 had anemia. None of the patients with heart failure, stroke, or acute myocardial infarction with a normal D-dimer level died within 90 days.

conclusionsIn this study, nearly half of all patients attending the ED had an elevated D-dimer level, and these patients were more likely to be admitted to hospital and to re-present to health services or die within 90 days. In this unselected ED patient population, elevated D-dimer levels were found to not only be significantly associated with venous thromboembolism, but to also be associated with infection, cancer, heart failure, and anemia.
