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

Acquired von Willebrand syndrome (AVWS) is a well-known complication of a monoclonal gammopathy with a potentially severe bleeding tendency. Treatment with von Willebrand factor (VWF)/factor VIII (FVIII) concentrate yields mixed results in controlling the bleeding diathesis, while the use of intravenous immunoglobulins may be effective. However, clear guidelines for the optimal management of AVWS are lacking. Therefore, we retrospectively analyzed the cases of AVWS secondary to monoclonal gammopathy at the University Hospitals of Leuven. We confirm the beneficial effect of intravenous immunoglobulins in IgG-associated AVWS. For IgM-associated AVWS, we observed better results with the administration of VWF/FVIII concentrate or a combination of therapies. Of note, one patient with IgG-associated AVWS did not respond to immunoglobulins and had mutations in the
