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

Venous thromboembolism may be the primary presentation in patients with polycythaemia vera (PV) and essential thrombocythemia. Most patients get diagnosed with polycythaemia vera after presenting with venous or arterial thromboembolism in the first place. Most patients tend to develop thrombosis just before or at the time of diagnosis, and this risk decreases over time. Patients aged >60 years with a history of previous thrombosis, elevated haematocrit, and leukocytosis are most at risk of thrombosis. We report a case of a 74-year-old patient presenting with shortness of breath for three days. A computerized tomography pulmonary angiogram showed bilateral pulmonary emboli with right heart strain. He underwent emergency EkoSonic™ endovascular system-directed thrombolysis (EKOS™, Boston Scientific, Marlborough, MA). The patient tested positive for the Janus kinase 2 gene mutation (JAK2), met two major and one minor criterion for PV, and was discharged home on oral anticoagulation. The Janus kinase 2 (JAK2V617F) mutation is quite common in patients with polycythaemia vera, thrombocythemia, and myelofibrosis, and these patients are at risk of both arterial and venous thrombosis, hence they require long-term follow-up.
