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

Immune thrombotic thrombocytopenic purpura (iTTP) is caused by ADAMTS13 deficiency due to anti-ADAMTS13 autoantibodies. Rituximab, an anti-CD20 monoclonal antibody, is often used to suppress these autoantibodies. This retrospective study, conducted in an iTTP cohort in Japan, evaluated the long-term efficacy of rituximab as off-label treatment for refractory or relapsed cases. A total of 252 iTTP patients with severe ADAMTS13 deficiency (< 10%) and its inhibitor were enrolled, and 169 episodes in 156 patients were analyzed. Sixty-five episodes with relapse or resistance to conventional treatment were treated with rituximab, while 104 episodes received conventional treatment only. The rituximab group had a significantly higher inhibitor titer than the rituximab-untreated group. During the median follow-up period of 3.9 years, there were 8 relapses in the rituximab group and 17 relapses in the rituximab-untreated group. The median time to relapse in the rituximab group (2.9 years) was significantly longer than that in the rituximab-untreated group (1.2 years). Relapse-free survival at 2 years was significantly higher in the rituximab group than in the rituximab-untreated group. The incidence of relapse at 5 years did not differ between the 2 groups. Rituximab reduced the risk of relapse in refractory or relapsed iTTP patients for 2 years.
