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

Thrombotic thrombocytopenic purpura (TTP) can rapidly progress into a life-threatening condition, thus the importance of appropriate diagnosis and treatment cannot be overstated. Until recently, TTP has mainly been diagnosed by clinical findings such as thrombocytopenia and non-immune hemolytic anemia. In addition to these clinical findings, however, reduced activity of a disintegrin-like and metalloprotease with thrombospondin type 1 motif 13 (ADAMTS13) below 10% has been accepted internationally as a diagnostic criterion for TTP. In the present guidelines, we have taken all of these criteria into consideration. TTP is classified as acquired if the patient is positive for anti-ADAMTS13 autoantibodies, and as congenital if ADAMTS13 gene abnormalities are detected. Fresh-frozen plasma (FFP) transfusion is performed in patients with congenital TTP to supplement ADAMTS13. Plasma exchange therapy using FFP is conducted in patients with acquired TTP to supplement ADAMTS13 and remove anti-ADAMTS13 autoantibodies. To suppress autoantibody production, corticosteroid therapy may be administered in conjunction with plasma exchange. Recent reports show that the monoclonal anti-CD-20 antibody rituximab is effective in patients with refractory or relapsed TTP.
